Digital baseband demodulator for binary FSK signals
초록
A digital logic demodulator for binary FSK signals is presented. The operation is based on the quadricorrelator which is known as an ideal frequency detector. The demodulator is especially suitable for high-speed application, and it can be easily implemented in integrated circuit. Computer simulation results show that the performance of the receiver with digital demodulator converges to that of analog quadricorrelator receiver as the number of mixing axes is increased and the optimum bandwidth depending on a modulation index is slightly wider than that of analog demodulator.
