Hello Achilleas, I tried out your idea and added an interleaver. While doing this, I got the error that really caused my trouble. I splited the coded sequenceinto 2 packets. And as I changed this, I worked fine, even better after adding an interleaver. So thanks for your idea. But that

The file source reads binary data out of a file and writes it into a gnuradio stream. So, if your data stream is floats, the file should be filled with floats, as it would be in your computer's memory. -josh On 09/16/2010 09:02 AM, mehmet kabasakal wrote: Hi everyone, I want to ask a

Hello Zhang, export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.6/dist-packages should probably fix the error. Make sure the path specified above exists and contains the python gnuradio packages. Cheers, Rakesh On Fri, Sep 17, 2010 at 8:01 AM, zhang wei weizh...@rdamicro.com wrote: Hi
