- A baseband digital narrow-band FM receiver,
called zero-intermediate frequency zero-crossing demodulator
(ZIFZCD), has been recently developed. This demodulator may
offer low complexity and simple implementation. However,
the bit error rate (BER) performance of the ZIFZCD is
inferior to that of the limiter-discriminator-integrate-and-dump
(LDI) demodulator. In this paper, a simple decision feedback
postprocessor (DFP) is proposed to improve the performance
of the ZIFZCD. Analysis and simulation BER results of the
ZIFZCD with the DFP are presented for minimum-shift keying
(MSK) and Gaussian MSK (GMSK) signals under additive white
Gaussian noise (AWGN) and mobile fading environments.
