摘要
A coded modulation scheme based on a low density parity check (LDPC) code is presented. A modified sum-product algorithm suitable for the LDPC-coded modulation scheme is also devised. Several simulation results show the excellent decoding performance of the proposed coding scheme. For example, an LDPC-coded 8PSK scheme of block length 3976 symbols achieves the symbol error probability 10(-5) at only 1.2 dB away from the Shannon limit of the channel.
