International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / This paper presents noncoherent limiter-discriminator detection and differential detection of FQPSK
(Feher quadrature phase-shift-keying) with maximum-likelihood sequence estimation (MLSE)
techniques. Noncoherent FQPSK systems are suitable for fast fading and cochannel interference
channels and channels with strong phase noise, and they can offer faster synchronization and reduce
outage events compared with conventional coherent systems. In this paper, both differential detection
and limiter-discriminator detection of FQPSK are discussed. We use MLSE with lookup tables to
exploit the memory in noncoherently detected FQPSK signals and thus significantly improve the bit
error rate (BER) performance in an additive white Gaussian noise (AWGN) channel.
