TRACK BUFFER IN A PARALLEL DECODER

摘要

A method (700) and apparatus (600) are described for performing 2<SUP>M-1 </SUP>parallel ACS operations to generate 2<SUP>M</SUP> path metric outputs and buffering the 2<SUP>M</SUP> path metric outputs in connection with a track buffer (112) in an Ultrawide Bandwidth (UWB) receiver for decoding a message sequence encoded according to a convolutional code. Contents of the track buffer are updated in accordance with Register Exchange and outputs from the track buffer can further be input to a voting unit (114) where a voting scheme can be applied and a decision rendered as to the originally transmitted message sequence.
