SYSTEM AND METHOD FOR DATA COMMUNICATION USING TURBO TRELLIS CODING MODULATION BY COMBINING CONSTELLATION SHAPING USING OR NOT USING PRE-CODING

摘要

PROBLEM TO BE SOLVED: To provide a system/method capable of attaining high performance by combining a TTCM coding system, shaping and pre-coding processing.;SOLUTION: Constellation shaping 702, the pre-coding 902 processing and a turbo trellis coding modulation(TTCM) coding method are combined to realize the system and method for binary coding communication capable of attaining high performance (attaining high coding gain with a shaping gain and improving the performance of an ISI channel by pre-coding at need).;COPYRIGHT: (C)2002,JPO
