All right, since euro on time, so far we, so it's 9 a.m.
Thank you for joining early in the morning, the SDR Devroom.
So it's going to be a full day of talk today, fully packed.
So hopefully we can keep this schedule and if you want to switch from one room to another,
we try to keep the schedule as planned initially.
Quick word of introduction, software radio and DSP.
Why do we have this title this year?
Every year, there's, for the last few years, there's been a couple of submissions to
hand radio and software-defined radio.
And unfortunately, the, for the organizers, had a hard time figuring out that that's two different fields.
It's got radio in it, but this year to try to differentiate
discrete time, complex sample, IQ processing from software control radio.
We added the digital team processing and, well, this year, that's the one that was selected.
So thank you for joining.
As I was not so kindly reminded, as Non-Hem Radio, we are not supposed to broadcast.
At least those of you who do not have a ham radio license.
So I just wanted to remind you that in case you wish to broadcast a signal, you must comply with
industrial scientific and medical band regulations, which I put back for you here.
So we've got some HF.
We've got some UHF, we've got some S-Band, we've got some C-Band.
So we've got plenty of ISM non-licensed bands to broadcast on and anyway, there's so many useful signals out there.
So that we have so much to receive already to decode that there's plenty of signal to analyze anyway.
The power levels are all defined limitation or updated power and duty cycles are provided in the IT regulation.
So I'm not going to read the whole hundred and sixty or something pages of ITU.
So start already by broadcasting only the ISM bands, then we comply with regulations.
And I'm going to show you actually how you can broadcast below the terminal noise, which means that even in all the other bands,
you all have the terminal, the noise limit, where you won't be detected anyway.
Another topic that I really enjoy about first them is not being a so-called scientific conference,
where actually people don't just want to show off results, but they really want to share how they actually result and how they did it.
So I checked on the first them, SDR dev room, all the contributors provided a GitHub,
so they took the reproduced very experiments.
And during the Christmas occasions, as I was reading, Dan Wong's book, comparing the Western politicians,
with their lower background and the Chinese politicians, with engineering background and high-tech,
probably much the same issues.
I was attracted to this paragraph where they highlight why Shenzhen is so in the Hong Kong, of course, is so successful.
And they argue that that it's a community of engineering practice,
whereas in the Western Silicon Valley, we're obsessed with creating new stuff and new invention.
Shenzhen is more about viewing blueprints and technological progress as training of various scientists,
manufacturers, 20 technologies, people, and process knowledge.
And I believe that at this gathering, we have a few people in Europe that are still in this mind of engineering as a way of life,
as a rather than just a day job for getting money.
So I really enjoy organizing this presentation with these people.
So a few highlights, this is a very personal summary of this year, of the last year,
which has no claim of exclusivity. It's just a few ideas I had from this year.
We've received, you might have heard, a Blue Ghost Mission, which landed on the Moon,
and so it was sponsored by the Italian Space Agency and the National Space Agency of America, so the NASA.
And what they did is they recorded global navigation satellite signals from the Moon, on their path to the Moon and on the Moon.
And they released the IQ data on the Sun website where you will find on the general record here,
all the data they collected.
And when they released the data, they had a meeting in Rome for two days.
If you're interested, I didn't find the release of a recording of the video conference,
but I do have a copy on my computer, if you're interested.
The first day was mostly political stuff from ESA, but the second day was really technical about the Blue Mission.
And they actually released the data and they opened a challenge asking, in one year, what are people going to achieve with these IQ streams?
So you can try by yourself, if you're familiar with or even if you're not familiar with Genesis processing,
that's a good way of getting attracted to this topic.
Another highlight for me, I've been waiting for nearly 10 years for a Spaceborne satellite, Nissan,
between the Indian Space Agency, Israel and NASA.
And it's been launched in July, 2025.
And this is an L-band, so 1.2GHz and S-band 3GHz satellite radar.
And I'm going to show you, actually, if we can receive the signals, and then you can actually have a lot of fun.
And at the moment, there's a whole collection of Spaceborne radars.
There's a couple of companies, Capella, Umbra, just fantastic.
If you read the BBC News, you're going to see a few of these pictures illustrating the BBC News.
They show 25 centimetre resolution radars, so all the weather, all elimination from 80 kilometers away.
Just fascinating.
This exercise is an origin project of Spaceborne radars.
There's a whole collection of Spaceborne radars broadcasting this information.
And again, Nissan, similarly to Sentinel-1, and to Lugar,
are claimed to publish the raw IQ streams, the little zero data sets.
At the moment, I have not seen data.
I think this week, I saw a few first files being uploaded on the Alaska satellite facility ASF.
You need an account, but it's free of charge, and I think you can give a dummy email address.
They're not going to verify.
Unfortunately for us, also, beyond these launches, I think many of you might have started
HDR with the low Earth orbital satellite from NOAA.
And that's finished now.
In August, the last broadcast of the NOAA weather analog satellite was switched off.
And at the end of since the 1970s of continuous observations of Earth using the analog signals from NOAA.
So now we left with, well, to the best of my knowledge, the M2 versions, CCSDS compliant satellite,
which, again, makes the entry level of HDR much steeper because we used to have an analog signal.
You just put a white band FM receiver, and you send this on your soundcard, you add something to listen it.
Now you need a 2PSK decoder, and then you get JPEG images, and you need to assemble the JPEG images to meet to one year to get to figure out how much M2 was working.
So that's an over challenge, and actually my colleague, to my left hand, spent a bit of time decoding the latest M2M2M,
because they defer each of the M2D for a little bit from the previous one.
So you need to adapt the decoding procedure.
One of the highlights for me, we have one new radio developer, where the CEO is on the back.
One of the highlights for me is new radio is table.
It hasn't changed forever, it doesn't change API, it hasn't changed configuration file.
For a second year in the rule, now I think we have the same new radio version on all distributions, on all operating systems.
In January, I taught in the Paris University 15 students, 14 of which were running Windows, unfortunately, this means that still 90% of the French students are running property reporting system,
and all of them, to the best of my knowledge, managed to install the new radio on their Windows computer and rental applications.
So that's very nice, because it means that instead of keeping on repairing things that used to work, which seems to be a habit in open source software, we now can focus on getting worked on.
There are a few of a few of the work that was achieved.
This is one example, again, with Toma Lavaren, using a new Windows scope for gathering SDR signals, I mentioned this yesterday at the both meeting.
So collecting data from a new Windows scope, of course, cannot be continuous, because your data rate from the new Windows scope to the computer is finite.
But yet, many applications, you can just gather burst of information, process of information, and then gather the next burst.
Whether it is for radar, where we have a reference signal in our surveillance signal, or in this case for the oscilloscope.
So we were collecting 100 megabit per second oscilloscope streams and analyzing the data.
Just for a little story, we were looking at this with Toma.
And at some point, I'm sure you all know that the Ethernet header is 800, so we were looking at all these frames with 800.
And at some point, as we were looking at the continuous stream, we had a 30 Ethernet type 887.
Anyone familiar with what this is?
No, we're not that advanced.
Actually, it's funny, it's a PTP header.
And the reason I mentioned this is that you'll see that a couple of presentations today are focused on the white rabbit, synchronization system, which is an enhanced PTP.
We're going to talk about it and how it relates to software different radio.
And it happens that in the lab, I have a white rabbit network, which was supposed to be isolated from the rest of the network.
And actually, you can use an oscilloscope to debug your IP tables errors, because, obviously, we have PTP frames leaking in the network.
And this we discovered when we're looking at our oscilloscope outputs.
As you are for topics, you all know that the radio runs flawlessly on embedded systems.
My colleague, Gwynel Goavec, has maintained a new radio functional build route.
A field balancer has kept open embedded the recipes for new radio working on open embedded.
So, we also have a new radio functional on your headless embedded systems.
We did some work with voice check on GRM17.
Basically, I just wrapped his C library into the new radio framework.
He tells me it's all functional.
I must admit, I did not check, but it's also another final application of the new radio.
And we're going to have a first presentation this morning about various digital communication schemes.
Next to M17.
So, it's going to be a discussion about digital communication.
Finally, because now we have a stable framework to work with.
Not only do we have the opportunity to work more on OT and out of tree blocks rather than keeping on repairing broken frameworks.
But also, there's a huge improvement on the documentation.
Barry Degen and a couple of his friends on the chat that you can join on the documentation.
The channel has been pulling together their activity about trying to give documentation about each and every block.
And giving examples on how to use these blocks.
So, really try to have a look.
I had a quick look at the statistics.
It's more than 130 entries now with about 10 files per entry.
So, it's a great entry point for getting started with a new radio and DSP in general,
because it gives you the opportunity of getting familiar with the practicals of each tool processing framework.
What's going to happen in the year?
If I look at last year, usually we have a few governing.
So, here you are at one of them.
The software you find radio first them at the beginning of the year.
During the summer, we should have the software you find radio academy.
Organized by Marcus.
In a pretty shuffin, always end up doing a fly.
Last year, there was no European new radio days.
It was a bit difficult to organize.
The previous year was lacking participants and especially speakers.
So, we decided to postpone to this year.
So, Silmore, organizing Lyon, an informal gathering of enthusiasts.
And hopefully next year, sorry, this year, we should have by the end of the year November or December.
It's not yet planned.
A European new radio day in Western France in Britain.
It's been organizing rain.
So, hopefully you can keep your schedule slot to join in Western France European new radio days.
This year, we had the wire conference in the Netherlands.
A very enthusiastic group of hackers meeting on all topics, including software in front radio.
There was an M17 meeting in Poland organized by boycheck.
And, of course, in September, our own September will have the new radio conference in the US.
So, that's going to happen.
This schedule for already scheduled and already announced.
There is a call for contribution open for the new radio conference in the USA.
No, I went in wrong direction. Sorry.
Right. So, that concludes my highlights from 2025.
So, just as a quick recap of today's program, which is fully booked,
we start with a contribution from the Open Research Institute,
which will actually be presented by Evernist about space and terrestrial digital communication.
Then, we have a few discussions about web-based software and radio communication.
I'll be sharing how I've been using the TWSDR signals to decode some of the very low frequency time transfer signals,
including Loran and Eloran.
How to collect data from China, from Russia, from Saudi Arabia, through the TWSDR.
And, we have the WSDDR presentation.
Hopefully, it's going to be a remote presentation because the offer of a speaker was not able to get a visa.
So, we'll try to make sure that the online presentation goes well.
In between to get ready, we have a surprise for you.
You're going to see an amazing signal, hopefully, broadcast live from deep space.
So, that's going to be a teaser for the presentation.
The last two before presentation about SDR for radio telescopes.
We have a few presentation about sync processing.
Daniel, we'll be talking about fear filter design.
We have another presentation over here.
And then, we have a few presentation.
I'm really happy that the certain colleagues accepted to join.
I would like to show you that there is a fantastic open source open hardware frame,
called Y-Trabbit, different familiar for synchronizing distributed computer networks.
And there are ideally suited for software different radio synchronization.
So, TWSDR is going to show us how, from my perspective, SDR is one big SDR, one very big SDR.
And I try to complement TWSDR's work to show you that you don't need to be a certain to be participating.
We have a couple hundred-two or a worth of FPGA, you can do it at home as well.
Andre will be talking about machine learning, because everyone is talking about AI at the moment.
And if Arist will be taking the mic again for presenting his work on the TWSDR.
And I'll be concluding about a sequel to last year's presentation about the max 2771.
So, the low-bit count A2D-converter dedicated to Genesis.
Thank you for watching.
