Hello to all,
First before I explain the problem a little backstory:
I am using a windows 10 PC and GNU radio v3.7.11 because if I go higher the bladeRF support doesn't work very well. I am trying to get a 'live' stream trough GNU radio.How I get this stream in GNU radio is as followed:
1) Stream with OBS to RTMP server
2) Use ffmpeg to get this 'live' stream to UDP
3)Use UDP source to put this in GRC
After this I modulate this with GSMK and 'send' it wireless with the use of an bladeRF x115. Then receive this with an another bladeRF x115 and demodulate it to play the videostream on vlc or an other mediaplayer. But first I try to get it working in a simulation program.
(for flowgraph picture see attached)
But when I try to run this simulation there are problems. I don't get a signal out.(see result1 picture). I have also tried to switch the fec decoder and packet decoder from place but then I don't get any signal in the f spectrum not even a 'zero' line and just a flat line in the time spectrum.
A fellow user of this platform advised me to use packets or frames and also said to use ?zero padding? because I use convolutional codes. But couldn't say how to use this.
If anyone knows how to do this pls help me and let me know.
Best regards,
Q
