A decoder for decoding convolutionally encoded precoding data is described. The precoding sequence consists of two subsequences t and b; the value of t corresponds to a convolutional encoder state at a particular time. The a priori probability Pr(ti) that the subsequence t has a particular value ti is...http://www.google.fr/patents/US6452984?utm_source=gb-gplus-shareBrevet US6452984 - Metric biasing for maximum likelihood sequence estimators
