Which manufacturers offer development kits for spread spectrum software radio, ie., high speed A/D with an appropriate front end, and programmable DSP with a compatible data rate?
Also requesting recommendations for graduate level textbooks on spread-spectrum communications.
Here are links I noted when this topic was presented recently at the local radio club: jtrs.army.mil
all unchecked by me.
A really nice, inexpensive solution is the GNU Radio USRP, designed by Matt Ettus. See:
It's really just a radio front-end/back-end: It uses your PC for data processing, which makes it a lot more flexible and cheaper than someone's DSP board. On the downside, there'd be a fair amount of effort to take anything you designed with it and turn it into a self-contained "box," but even this isn't that hard these days... there's a guy out there who has a kit that does this, although I'm not able to lay my hands on it at the moment (it's an HF rig using a small form factor PC running embedded Windoze). Anyway, the point is that for research, it's hard to beat a USRP on a price/performance basis assuming you already have access to a decent PC.
Dixon's books are classics...

Mmm... I don't know! I don't have a copy of the newer (3rd) edition here -- it's on order! -- and the second one is presently 240 miles away.
Thank you. Does it cover calculating channel capacity from entropy considerations in the presence of noise?
