Hi I am new to gnu radio and am trying to understand how a packet transmission happens using GNU radio
I am looking at benchmark_tx.py and benchmark_rx.py.I understood that this is the top block which uses transmit_py and receive_py as the underlying blocks. I am using DQPSK for modulation.I went through dbpsk.py to understand how the modulation is done.What i couldnt find out is where is the bit stream modulated with the carrier frequency.From the theory of QPSK i know that the phase of the carrier is changed depending if the bit that modulates it is '1' or '0'. I cant figure out where this happens in the code. My eventual aim is to put a block for BPSK in place.Any pointers on how to do it will use greatly appreciated Please help me Manav -- Posted via http://www.ruby-forum.com/. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
