Equalization of Time-Varying Dispersive Channels via Sequence Estimation.

Abstract

Adaptive maximum likelihood sequence estimation (AMLSE) has been shown to be an effective mitigation technique for high data rate links against the deleterious effects of intersymbol interference resulting from rapidly time-varying and frequency selective fading channels. It was demonstrated that significant performance improvements can be obtained through the use of AMLSE receiver demodulation in comparison to conventional (non-delay spread specialized) receivers and even decision feedback equalization receivers. In addition, several important channel related receiver anomalies which introduce symbol timing ambiguities were identified.
