Re: [Discuss-gnuradio] [GSoC] It has begun

Hello Everyone, I'm Manu, a graduate student at Indian Institute of Technology, Bombay. I'm pursuing masters in Electrical Engineering specializing in Communication and Signal Processing. My proposal on LDPC codes has been accepted for GSoC. You can look into the proposal

[Discuss-gnuradio] Here's an interesting bug

That I suspect will be hard to fix. If you run grcc in something that doesn't have access to the X display, it barfs: Traceback (most recent call last): File "/usr/local/bin/grcc", line 27, in from gnuradio.grc.python.Platform import Platform File "/usr/local/lib64/python2.7/site-pa

[Discuss-gnuradio] gr-osmosdr build fails today

GR-OSMOSDR was failing starting sometime today, since "master" of their source code base has now been updated to the 3.7 API, and of course build-gnuradio now uses "maint", which the current "master" GR-OSMOSDR will no longer build against. So, now, the gr-osmosdr code in build-gnuradio check

Hi folks, I have just built the 3.6.4.1, 3.6.4.2 and 3.6.5 tarballs on the latest KUBUNTU (13.04 raring ringtail) with these sequence of shell commands : *$ ./build-gnuradio -v prereqs** ** **$ mkdir build** ** **$ cd build** ** **$ cmake -DENABLE_BAD_BOOST=ON -DPYTHON_EXECUTABLE=/usr/bin/pytho

Could this be made an online streaming live so that people sitting all around could also watch and learn. Are there any plans to organize such events in southern/eastern parts preferably at UNIVERSITY OF FLORIDA, GAINESVILLE, FL. -Regards, Ankan Roybardhan. On Thu, May 30, 2013 at 5:48 PM, Jon

[Discuss-gnuradio] GNU Radio presentation at Virginia Tech, Monday

Hi everyone, We've been holding GNU Radio Hackfests every now and then in the past. These are meant for the main, core developers to get together and develop new material and features, fix bugs, and figure out where we want to go as a project. You can see some of the output of our last Hackfest fr

Hello again, I've already implemented the modulation schemes i'm writing above, plus the manchester encoder. No i'm trying to design the biphase space (fm0) encoder. For the manchester i used 2 square sources, one for the data and another one for the clock with the double frequency and i use an XOR

Hi everyone, I'm trying to estimate the channel frequency response in narrowband in benchmark. But the result I get looks like a sine wave. Anyone knows how to do channel estimation in narrowband? And in GNU Radio and USRP transmission, when the carrier frequency is added and taken off? Thanks

[Discuss-gnuradio] Sampling rate in USRP 1

Hi, I am using USRP 1 for an application. I am using complex baseband representation, so i am setting bandwidth almost equal to the sampling rate. But many times i see that when i set the sample rate I get target sampling rate is different from actual sampling rate. I checked the wiki, it says

Re: [Discuss-gnuradio] channel estimation in gnuradio narrowband

Hi Alex, yes, I'm using the original generic_mod_demod.py, and just adding a file_sink after the time_recov block, so there is a freq_recov before. But thanks all the same! :) Ada Date: Thu, 30 May 2013 00:28:45 -0500 Subject: Re: [Discuss-gnuradio] channel estimation in gnuradio narrowband Fr
