Re: [Discuss-gnuradio] FOSDEM attendee? Re: 802.15.4 CSS PHY

[Felix W.]

Hi,

that was me ;). I also talked to Bastian Bloessl and we agreed that I will create a pull request to gr-ieee802-15-4 once I finish my master's thesis and have it all cleaned up. In the meantime, you can find my fork of Bastian's repo here: https://github.com/fewu/gr-ieee802-15-4. The branch with my work is called css_phy. Currently I'm working on the synchronization for the CSS PHY. My previous work focused on evaluating PHY and MAC performance with the assumption of perfect sync. It's also not really complete yet (e.g. preamble and PHR are dropped in the receiver because their content is assumed to be known) and endianness might be wrong at some points. But I will try to fix that in the next weeks.

Feel free to contact me if you have any questions!

Greetings

Felix

Hi list,

this is just a shot in the dark, but I forgot to get the name of an
attendee during the Internet of #allthethings talk.

If you are, or know who is, the person who said he had implemented an
802.15.4 CSS PHY in the question period, please get in touch with me
or pass on the message.

It would be very beneficial to collect the 15.4 related work into one
repository to reuse some amount of code. The 800 & 900 MHz PHY would
be very useful to have in there and would be relatively painless to
design. The CSS PHY is obviously much more interesting :-)

Also, in particular, any future UWB PHY designers would be helpful.
The SDR hardware for such a PHY might be a bit pricey. Even a
unit-test driven PHY design would be helpful or simulation.

As of this point, I have not heard of any major silicon vendors are
even speaking about offering an UWB PHY, so it would be nice to be
ahead of the game.

Cheers,

C
