ABSTRACT:
A concatenated trellis coded modulation and linear block (e.g., Reed-Solomon) encoding scheme splits data to be encoded into two data streams, one of which is both linear block encoded and trellis encoded, and the other of which either remains uncoded or is encoded with a weaker strength linear block code. The coding scheme requires the use of a special decoder which decodes the trellis encoded data first, and then uses the resulting information to decode the non-trellis encoded information. In embodiments using linear block coding for the non-trellis encoded data stream, the relative strengths of the two linear block encoders are selected to balance the resulting code, thereby maximizing coding gain and efficiency.
