Hi I am wondering why most of file transfer use FSK (De)Modulation scheme ?
There is also PSK, QAM scheme, but I can’t use them for file transferring. General example of file transmission using GMSK’s flow graph like below: Tx ) File source -> Packet encoder -> GMSK mod -> Osmocom sink Rx ) Osmocom source -> GMSK demod -> Packet decoder -> File sink I tried to replace GMSK to QAM or PSK scheme, however it doesn’t work. I couldn’t get any file,but when I saw Rx GUI FFT Sink, I could see signal is sparked at Tx started. How can I use PSK or QAM for file transfer ? Thanks. _______________________________________________ HackRF-dev mailing list [email protected] https://pairlist9.pair.net/mailman/listinfo/hackrf-dev
