Abstract:
A process for estimating successive values of digital symbols which can each take M different possible values, on the basis of the successive values of digital samples each of which results from the combination of at most L successive symbols. This process includes a stage by stage progression through a trellis of the Viterbi type with Mk states, with k being less than or equal to L−1. All the stages are respectively provided with aggregate metrics.
