Abstract

Methodology, and associated circuitry, for encoding and decoding an incoming data stream utilize a coordinated code constellation that effects robust signal detection in the presence of channel interference. The encoder partitions the incoming data stream into contiguous data segments in proportion to the number of levels for a given coordinated code. Each data segment is mapped with reference to the coordinated code to signal levels suitable for transmission over a plurality of channels. The decoder measures the received signals on the channels and estimates noise statistics for the channels. A metric relationship engendered by the coordinated code is evaluated with reference to the received signals, estimates to the received signals, and the noise statistics. An output data stream is then generated based on the evaluation of the metric.
