Abstract
Recently, a digital baseband receiver called zero-intermediate frequency zero-crossing demodulator (ZIFZCD) was developed for digital FM signal detection. ZIFZCD is applicable to many worldwide mobile and personal communications systems. In addition, ZIFZCD offers lower power consumption and simpler implementation, compared to the conventional analog implementation [e.g., a limiter-discriminator integrator and dump (LDI)] and the conventional digital implementation [e.g., the cross-differentiate-mulliply demodulator (CDM)]. An objective of this paper is to introduce the ZIFZCD and report the bit-error rate (BER) of the ZIFZCD under both static and fading environments. The analyzed and simulated BER results show that the ZIFZCD is comparable to the conventional CDM for a narrowband digital FM with modulation index 0.5, and the ZIFZCD is significantly better than the CDM for a wideband digital FM with modulation index larger than 1.5. © 1996 IEEE. © 2011 Elsevier B.V., All rights reserved.
