A method () and apparatus () are described for performing parallel decoding in connection with 2parallel ACS unit in ACS unit (), track buffer () and voting unit () in an Ultrawide Bandwidth (UWB) receiver having a parallel trellis decoder for decoding a message sequence encoded according to a convolutional code. Outputs from the track buffer can be input to a voting unit () where a voting scheme can be applied and a decision rendered as to the originally transmitted message sequence.

Parallel decoder for ultrawide bandwidth receiver

A method () and apparatus () are described for performing decision voting in connection with a parallel ACS unit () and track buffer () in an Ultrawide Bandwidth (UWB) receiver having a parallel DECODER for decoding a message sequence encoded according to a convolutional code. Outputs from the track buffer can be input to a voting unit () where a voting scheme can be applied and a decision rendered as to the originally transmitted message sequence.

Decision voting in a parallel decoder

A method () and apparatus () are described for performing 2parallel ACS operations to generate 2path metric outputs and buffering the 2path metric outputs in connection with a track buffer () 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 () where a voting scheme can be applied and a decision rendered as to the originally transmitted message sequence.
