Re: [Discuss-gnuradio] re: Low cost hardware option, the "total GNUsolution"

Hi All, I've been following the (lowcost) GNU SDR HW development in progress since it started. I sure do not oppose to what you are doing and hope you succeed, but is it practical today? Some questions about the product that you are developing: 1: Will a prebuilt and tuned GNU SDR board (+ da

Re: [Discuss-gnuradio] Greeting and a question

Hi Tom, I am giving up on that idea, as much as I love my old boards, it seems like porting the Gnu Radio to that processor it is not worth much at this stage since the processor is too slow for any serious processing compare to modern Cortex A8 based processors. I think I have to learn to wa

Re: [Discuss-gnuradio] OFDM on USRP2

Hi, I updated the OFDM example. You can find it at http://www.cs.ucsb.edu/~veljko/downloads/ofdm_example.tar.gz It supports both USRPs and the UHD driver. I get pretty bad performance with UHD receiver for some reason. Any ideas? Cheers, Veljko On Tue, Jan 11, 2011 at 9:26 PM, Guanbo wrote

One way is to use a throttled file source sink, and use someones capture file. I have some here you can download online. http://kd8eyf.org/capture_files/ Sent from Yahoo! Mail on Android ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org

[Discuss-gnuradio] Porting benchmark_tx/rx to UHD for use with E100

Hey all - I'm attempting to make the necessary changes to get benchmark_tx/rx.py working on the E100 with UHD. My end goal is to preserve backwards-compatibility with non-UHD runs since the old USRP[1,2] drivers will remain in GNURadio for a bit longer. As it turns out, this requires very little

Re: [Discuss-gnuradio] OFDM receiver on USRP2

Hi, I feel like the output of coarse frequency offset is very inaccurate. Or probably it is not directly related. For best test, I tried higher resolution of subcarrier bandwidth by selecting the large FFT length, high Interp/decim rate, as follows: @TX: $ sudo python benchmark_ofdm_tx_new.py
