Abstract :
In this paper a novel digital demodulation method for CPFSK and its realization are introduced which is called phase quantization demodulator (PQD). PQD is a improvement on zero intermediate-frequency zero-crossing demodulator (ZIFZCD). Comparison between PQD, ZIFZCD and conventional cross-correlator is done and the result show that the PQD has less calculation which result in less complexity and power consumption
