SYSTEM AND METHOD OF DATA COMMUNICATION USING TRELLIS CODED MODULATION OR TURBO TRELLIS CODED MODULATION IN COMBINATION WITH CONSTELLATION SHAPING WITH OR WITHOUT PRECODING WHEN USING CONCATENATED CODING SCHEMES OR WHEN WORKING IN A NON-ERROR FREE OPERATION POINT

摘要

A technique that combines either a trellis coded modulation (TCM) coding scheme or a turbo trellis coded modulation (TTCM) coding scheme with constellation shaping and precoding schemes, and further in combination with concatenated coding schemes or when working in a non-error free operation point, to implement a binary coded communication system and method that can achieve high performance (high coding gains achieved in combination with shaping gain, and when necessary, also with high performance in ISI-channels via precoding).
