Hello again, Sorry, I am not familiar with GNU Radio and I just keep coming up with new questions...
I am simulating a transmission using IF - Base Band frequency conversion and a channel_model block introducing noise and frequency offset. As I said I am particularly interested in the Costas loop performance. So first of all I would like to make sure frequency_offset parameter really stands up for a slight deviation between theoretical transmission frequency and the real frequency at which the signal is sent. What is the unit of this parameter? Hz? I would also like to have an idea of the approximative maximum frequency_offset value that can be corrected by the Costas loop. I am asking these questions because when looking closely at the Costas loop NCO frequency value I realized it is far from correcting configured frequency_offset and this even for small values. -- View this message in context: http://www.nabble.com/Trace-mpsk_receiver_cc%28%29-tp17605464p17650469.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
