A novel fractionally-spaced MLSE receiver and channel tracking with side information

The performance of adaptive MLSE receivers depends upon channel estimation accuracy and the metric being optimized. In this paper, channel estimation is improved by estimating the transmission medium response, using pulse shaping side information. An optimal fractionally-spaced MLSE metric is formulated in terms of the pulse shape autocorrelation and the transmission medium response. Performance gains are quantified for the IS-136 (D-AMPS) digital cellular system.
