Abstract :
Maximum-likelihood sequence-estimation (MLSE) performance on the D-AMPS 1900 channel is evaluated through simulations. A channel-tracking algorithm of least-mean-squares (LMS) complexity is used in conjunction with the MLSE. It is shown that the receiver specification points for D-AMPS 1900 are met and that performance can be further enhanced with fractionally spaced equalization and/or receiver-antenna diversity combining
