fsk demodulation algorithm
Hello,
I want to search for some demodulatin algorithms for burst FSK.
I had built a FSK transmitter and two FSK receivers to do burst data communication between two computer via wireless channel. The data rate is 9600kbps/19200kbps. One receiver is analog demodulator and using philips SA605 fsk demodulation chip, the other using ADC/FPGA to do the fully digital FSK demodulator. The total carrier frequency offset is not high (about 1kHz). The analog demodulator work well, it's sensitivity is about -113dBm. The fully digital demodulator's sensitivity is only -103dBm for i am not familiar to burst FSK demodulation algorithm.
In burst FSK receiver, the PLL technique may be not suitable, Anyone has the idea for the burst FSK demod?
thanks
