Hi All, i want to implement psk transceiver in C. i don't understand the python code that gnuradio implement psk. for the transmitter i only need to map the bits data to psk constellation to get i/q sample. but for receiver because of the phase error between receiver and transmitter should i add some pilot symbol to the transmited signal such as add several bit '1' at the bigging of the transmitted data. then use the pilot symbol to estimate the phase error. is there any better way? this seems not related to gnuradio but i think post here will have answer.
