Hi: I have some problem about dbpsk and bpsk using benchmark_tx/rx.py with some modification.
My experiment set up was that the transmitter waits for a time delay (0.5 s) after sending a packet. It means that we transmit data discontinuously. If we using dbpsk modulation, we can successfully receive every packet. But if we removed the differential encoder/decoder (equals to bpsk modulation), we uaually lost some packet (almost half of the data lost). However, when we transmit data continuously,the bpsk modulation seems work fine and we can successfully receive every packet. My problem is that what reason causing the bpsk modulation can not successfully receive packet when transmit data discontinuously. Could anyone have any idea about it, please let me know. I am deeply appreciative.
