Re: [Discuss-gnuradio] Using the MIMO port for serial comm. to a Virtex5 board

Hello, I'm most likely having a clock issue because I cannot get any data transfers going between the USRP2 and GTPs on the V5. A few questions: - I'm not quite sure I understand the 10MHz reference clock idea, or its usage; I looked through the HDL and everything on the FPGA is running at 100MHz.

[Discuss-gnuradio] Re: USRP2 802.11 BBN code on the TX side

Thanks Doug, there is hope! I'm going to hook it up to a spectrum analyzer today and make sure everything is okay out of the USRP2. If you think of anything or get back to your office just let me know, thanks! - George ___ Discuss-gnuradio mailing list

[Discuss-gnuradio] Diving into BBN802.11 code: compiling & working

Hi all I'm a telecommunication engineering student from Elche, Spain (www.umh.es) and this is my first time writing here. Nowadays I'm doing my final degree project related to GNU Radio & USRP2. The goal of my project is develop an 802.11a (OFDM) transmitte

[Discuss-gnuradio] problem of compiling FPGA bin files.

Hi, I tried to use Xilinx ISE 11.1 to open project "usrp2/fpga/top/u2_fpga/u2_fpga.ise".There are some files missing,such as"fifo_generator_4_1.v" . And there are errors when implement design... == ERROR:ConstraintSystem:59 - Constraint [u2_fpga.

[Discuss-gnuradio] Ofdm spectrum

Hello everyone, I was trying to implement some OFDM transmission with a rfx2400 without using the ofdm code that comes with gnuradio but creating my own one. I make a 256 bean Ifft transform after the windowing, and I've tried two different types of window the rectangular one (aka no window :)

[Discuss-gnuradio] No exception... but no transmission

Hi all, Actually i pasted this post before but according to the rules, since i was not subscribed to the GNU mailing list i have to send it again. I'm new to Python and gnuradio, so please help me. My problem doesnot show any exception so i cannot trace it. However, i created a program to tran
