Abstract :
A novel scheme of a `pseudocoherent¿ FSK demodulator is proposed. Computer simulation and hardware-measured test results are given. It is shown that this new scheme gives lower bit error rates than the noncoherent demodulator, but has a comparable circuit complexity. Furthermore, its filtering requirements are minimal; this fact makes it especially suitable for a low-cost integrated FSK modem.
