I want to demodulate signal generated by CC1101 with USRP and Gnuradio, and my signal information listed below: Modulation : GFSK Preamble 4 bytes sync 4 byte Packet length fix Manchester Disable CRC Check no White spacing Yes Data rate: 9600k Bandwidth :58036Hz F(IF) :380860 Hz Carrier Frequency: 450Mhz Fdeviation: 5157.5 Channel:49988Hz Sampling Rate 1MHz I try to use one of the sample in internet by demoudulating with QuadDemode also I used GFSK Demod too in both of them I could not detect any frame. Could you please check attached picture and see If I missed anything . Thanks, Behnam ---
