Transmission method combining trellis coded modulation and low-density parity check code and architecture thereof

Abstract

The present invention discloses a method combining Trellis Coded Modulation (TCM) and Low-Density Parity Check (LDPC) code and the architecture thereof, which incorporates TCM with LDPC code having better error-correction capability to promote transmission quality and to define TCM of different transmission rates. Further, TCM can utilize less number of states to outperform the conventional spreading so that the hardware complexity in high-speed transmission can be reduced.
