Abstract
A method and apparatus for detecting and decoding multiple or single users in a TDMA system where multipath propagation is present. A TDMA receiver may receive a one dimensional TDMA signal stream and may include a maximum likelihood sequence estimation (MLSE) stage to detect users from the received one dimensional TDMA signal stream. A decision feedback equalizer receives the postcursor portions of the TDMA channel from a channel estimator and an estimate of the postcursor portions of the transmitted signal from the MLSE stage. The decision feedback equalizer (DFE) truncates the interference in the received TDMA signal stream by cancelling the postcursor portion of the channel. The MLSE stage operates on the truncated TDMA signal stream to detect users.
