Abstract

The paper describes a new Japan digital cellular receiver that uses an adaptive truncated maximum-likelihood sequence estimation (MLSE) equalizer. The receiver employs a channel estimation and symbol synchronization procedure that uses the known phase shifts between successive symbols in the synchronization word. Per-survivor processing is used to track the channel variations and carrier frequency offset. Simulation results are presented for multipath Rayleigh fading channels having various delay profiles. Comparisons between a regular symbol-spaced truncated MLSE receiver and a fractionally-spaced truncated MLSE receiver are also furnished
