Abstract
Systems and methods are provided for decoding a vector from a communications channel using a non-binary decoder. The communications channel may correspond to a wired or wireless channel. A message passing process computes R messages corresponding to a variable node of the non-binary decoder. Decoder extrinsic information is formed for the variable node by combining the R messages. The decoder extrinsic information is provided to a soft-detector.
