FWIW, I just compiled 0e32fca on opensuse. It builds just fine, but I'm failing all the polar tests. Yeah I have scipy installed. I'll start a new thread on that when I've totally given up debugging. But the code on that rev is buildable on my PC. On Sun, 21 May 2017 08:13:28 +0200 "Ralph A. Sc

You need to use USRP "issue_stream_cmd" method (mode: STREAM_MODE_NUM_SAMPS_AND_DONE). It's allow to receive burst of data by USRP timer. If you work in GRC: 1) Disable streaming autostart for "UHD source" 2) Create your own block which will periodically issue stream commands (yes, you need to pass

If you don't need high accuracy just "filter" received samples by rx_time or use "Keep M in N" block where N = (samp_rate * 3 sec) and M = (samp_rate * 1 sec). 2017-05-21 12:24 GMT+03:00 Paul I. : > You need to use USRP "issue_stream_cmd" method (mode: > STREAM_MODE_NUM_SAMPS_AND_DONE). It's allo

[Discuss-gnuradio] IEEE 802.11 a/g/p transreceiver module - Number of symbols per frame?

2017-05-21 Thread Qurat-Ul-Ann Akbar
Hi, I want to look at the number of symbols copied for *each frame received *in wifi_rx flow graph. I have been trying to understand how the start of each frame is calculated and by looking at the code it seems like its being done in the wifi sync_short block where the auto correlation coefficient

It seems opensuse runs an old rev of gsl. Here are the relevant file names and revs: gsl 1.16-74 gsl-devel 2.3-9.1 libgsl19 2.3-9.1 libgslblas0 2.3-9.1 python-pygsl 0.9.5-2.30 python-pygsl-devel 0.9.5-2.30 Using the science repo, I can upgrade gsl to rev 2.3. Yast will have to deinstall a number
