[Discuss-gnuradio] Re Bottleneck of GNURadio to handle wideband 802.11b signals.

Hi Eric/Matt,   We are trying to build GNURadio based channel emulator/TX-Rx chain for 802.11b signals but the as you guys know USB is bottleneck right now to process wideband sampled signals. Do you guys see anyway in future that this bottleneck be removed and all the data sampled from wideb

[Discuss-gnuradio] FC6 fusb compile breaker

After upgrading to FC6, usrp/host/lib/fusb_linux.cc fails to compile (can't find linux/compiler.h). Turns out for me, that include file isn't needed at all (trivial patch attached). I wonder if I've broken something by removing it, or if other systems need it? fusb-fc6.patch.gz Description: G

RE: [Discuss-gnuradio] Sample rate for source_noise and source_vector

Thanks Therefore the USB rate is automatically adapted by the interpolation/decimation factor! I thinked that it was us that have to adapted the different parameters (interpolation/decimation and sample rate over USB). Thank you Julian -Message d'origine- De : Eric Blossom [mailto:[EM

[Discuss-gnuradio] gain slider issues

I'm having some python coding issues with a slider I'm trying to implement. The code is based on usrp_wfm_rcv_pll.py, which uses the powermate to adjust either frequency or volume. I would like to replace the volume slider with a gain slider, which exists in the original but which is not cont

[Discuss-gnuradio] Sample rate for source_noise and source_vector

Hello, When you specify a signal_source, you have to set up the sample rate. But with the noise and vector sources you do not have to specify this parameter. What is the sample rate in the computer -> USB when we generate a noise or generate data from a list/file? Thanks _
