In my spare time I am working on getting Linux running on the ARM on the Lyrtech board. Since I don't have enough spare time, I only have Linux running on the ARM via root over NFS, but it is a start. I have a web page where I keep track off my efforts: http://ossie.wireless.vt.edu/trac/wiki/SffsdrLinux This is only for people experienced with embedded Linux at the moment. If you are interested in trying this out, ping Lyrtech Tech support and ask for a utility to restore the flash to the factory settings. The board should run GNU radio once Linux is running OK.

I, for one, would love to see them. I, too, am writing a paper that will (among other things) discuss GNU Radio and USRP and alternatives to them. I'm happy to provide a summery, on or off-list, of what I've learned / written.

I have two of the Lyrtech boards and with the develpment tools for DSP chip and FPGA. Using Matlab simulink, and code generation, etc. for rapid prototyping this is just about ohh, one hundred grand.. The Matlab is shared license at work as is the DSP and FPGA development tools but this is well out of reach of most.

[Discuss-gnuradio] Need info for paper.
I'm co-writing a paper on the use of GNU Radio. Because I'm inclined to use 'Open Source' solutions, GNU Radio and the attendant DSP library, was for me about the only choice I would have made... However, in the paper I'd like to at least make some attempt at indicating any 'alternatives', if there are any in the Open Source arena, or parish the thought, cost-money type packages. If anyone has done a more detailed evaluation and perhaps has a chart depicting features, that would be good. Also, a while ago, I saw someone who had put together a 'graphical' interface, where one could construct a DSP processor using graphical means, and setting various parameters using a GUI. I have not had the time to really keep up on that sort of thing, but if there is someone who has something that works, I'd also like to know about that. For those who have information, and send me a release, credit will be made in the paper for their contribution.

Hi John, There are a couple other SDR-type platforms in the academic world... but none really come close to the code base of GR IMO. Rice has WARP: http://warp.rice.edu/ Kansas is developing the KU Agile Radio: http://www.ittc.ku.edu/techreview2005/presentations/Minden_Agile%20Radios.ppt UCSD has the CalRadio: http://calradio.calit2.net/ WARP is a very expensive platform IMO, and they are not as modular as GNU Radio. I would say GNU Radio has far more in the PHY layer, and WARP has 1 PHY (OFDM) + a bunch of MAC implementations. The KU Agile radio is still pretty new, Prof. Minden gave a talk here about it last semester and it seemed the hardware was pretty concrete but the software was still in progress... which is what truly separates SDR platforms :) CalRadio v1 is strict 802.11 based, and the PHY is not flexible. I think their goal was to keep the PHY in hardware and swap out daughterboards with different PHYs that you could re-program the MAC on. - George John Clark wrote: I'm co-writing a paper on the use of GNU Radio.
