  • MAP detector with a single state metric engine
    Patent number: 7958437
    Abstract: A maximum a posteriori detector includes a single state metric engine that performs forward and backward processing to produce forward and backward state metrics. The state metric engine includes a plurality of processes that each perform both the forward and the backward processing operations. The system further includes memory that stores the forward and backward state metrics that are produced by the engine in appropriate orders for the forward and backward processing. A number of multiplexers provide the appropriate branch metrics and apriori values to adder strings in each of the processors in accordance with an associate decoding trellis.
