More Information
Summary:Apparatus and methods are provided to decode signals from a communication channel to reconstruct transmitted information. Embodiments may include applying a plurality of decoders to a code, in which reliability values are provided to a decoder such that the decoder receives the reliability values determined by and provided from only one other decoder of the plurality of decoders. A valid codeword may be output from application of the plurality of decoders to the code.
