ABSTRACT
Low density parity check ( LDPC ) code is flexible in construction, simple in decoding, excellent performance and high spectrum efficiency. This paper introduces the LDPC codes and bit-interleaved coded modulation with iterative decoding (BICM-ID) scheme, proposed an LDPC codes as component codes in BICM-ID scheme is applied to Multi-Level Quadrature Amplitude Modulation (M-QAM) in the OFDM communication system, and given its log-likelihood ratio belief propagation (LLR-BP) decoding algorithm. Finally, according to the characteristics of the digital broadcast channel, system performancebasedonLDPC-BICM-ID scheme is compare with the rate compatible punctured convolutional code (RCPC) scheme over MF and HF radio broadcasting channels. Simulation results show that the proposed scheme is better than RCPC-MLC system.
