International ClassesH03H 007/30H04B 007/10 AbstractA digital communications receiver provides joint MLSE equalization and diversity combining. A plurality of diversity branches are processed to produce complex receive data samples and synchronization information. Channel estimators then form channel estimates from the data samples and synchronization information. The data samples and channel estimates are then used by pre-processors to produce metric multipliers. Finally, the metric multipliers are combined with hypothesized data sequences to generate and accumulate metrics using a sequence estimation algorithm to produce a demodulated data stream.Other References
