摘要： A vector decoder for detecting symbols transmitted along a communication channel is disclosed, as is a method for decoding symbols. The decoder includes at least two pairs of decision feedback equalizers and noise predictors operating on a plurality M of vectors of symbols being detected, a path storage unit, a metric determiner a sorter and a path builder. The vectors are ordered in accordance with quality levels and each noise predictor estimates the noise associated with its associated vector. The path storage unit stores M of the ordered vectors, each vector being of length L. The metric determiner is connected to the output of all of the decision feedback equalizers and the noise predictors and produces a performance metric for each of Q branches extending from each vector. Each branch is associated with one of Q possible symbol values. The sorter is connected to the output of the metric determiner and sorts data, formed of a) the symbol values and b) the vectors which they extend, in accordance with their performance metrics. The sorter also orders, from the M*Q performance metrics, the data having the M best performance metrics. The path builder is connected to the output of the sorter and associates the ordered data with the appropriate ones of the previously stored ordered vectors.
