摘要：
A sequence estimator is described. In one embodiment, the sequence estimator includes a plurality of maximum a posteriori probability (MAP) decoding engines each arranged to process a series of windows of a transmitted signal where state metrics produced for an end of one window by one decoding engine are re-used for the initialization of a state metric calculation process performed by another decoding engine on another window of the signal.
