  • Method and apparatus for performing data sorting in a decoder
    Patent number: 6233291
    Abstract: 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.
    Type: Grant
