Maximum-likelihood sequence-estimation (MLSE) performance on the D-AMP
S 1900 channel is evaluated through simulations. A recently proposed c
hannel-tracking algorithm of least-mean squares (LMS) complexity is us
ed in conjunction with the MLSE. It is shown that the receiver specifi
cation points for D-AMPS 1900 are met and that performance can be furt
her enhanced with fractionally spaced equalization and/or receiver-ant
enna diversity combining.
