Along those lines are Lyrtech's boards (the Small Form Factor (SFF) SDR) and TI has something similar. These are almost all FPGA-based SDR devices, and I'm not sure what kind of software you get with them to do any communications. And they are very expensive.George Nychis schrieb:Some of these seemed pretty 'expensive' to get into... the use of ASICs, and the like, also, they seem to be directed to pretty specific implementations of transmissions, even though one could conceivably load in a new chunk of firmware 'on the fly' perhaps...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.
Gary's new design uses an Intel chip, though I'm not sure where they are on production. I've seen them work, though, and they provided a nice demonstration of the KUAR at the IEEE DySPAN conference in Dublin last year. I hope to get them back for this year's, too.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.Looked interesting, but did have this overhead of ASIC, and buying the attendant boards.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 :)Looks closest to what I'm doing... albeit not with a PPC core...
