Abstract
A MAP detector system operates in a parallel mode for on-the-fly operations and in a serial mode for error recovery operations. In the parallel mode, a plurality of Viterbi operators process a block of input sampled data in parallel. In the serial mode a selected forward Viterbi operator and two associated reverse Viterbi operators process the entire block of data, in order, to produce soft decision data.
