Hello everyone, I am trying to plot the RF power spectrum obtained a during packet reception. For this, I have merged usrp_spectrum_sense.py with bbn_80211_rx.py. To make it easier to understand, I have put a figure illustrating the resultant flow graph at http://www.cs.wisc.edu/~shravan/pkt_energy.jpg
usrp_c is used as a source and then there are two separate paths that the samples take. One gives us the power spectrum and the other tells us whenever a packet is received. I am basically interested in knowing the output of the power spectrum part when a packet is received on the bbn part of the flow graph i.e. I want to "plot the power spectrum for exactly those samples which result in a packet being received on the bbn part of the flow graph". The problem I am facing is how to correlate the samples i.e. how would I know which samples resulted in a packet and then plot the spectrum for those samples ...? Can I keep track of something like a global sample number which I can use .. ? The issue seems to be complicated because of how scheduling is performed .. I would appreciate it if you can throw in ideas .. Thanks for the help, Shravan _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
