A Joint Source-Channel Coding Scheme Using Low-Density Parity-Check Codes and Error Resilient Arithmetic Codes

摘要

In this paper, we propose a novel joint source-channel coding (JSCC) scheme that combines error resilient arithmetic codes (ERAC) and low-density parity-check (LDPC) codes. In the proposed scheme, the error detection capability of ERAC is exploited by the bit-interleaving technique to improve the performance of LDPC decoder, and the overall decoding performance. Simulation results show that the proposed approach achieves significant performance gains with respect to the separated decoding techniques, with additional advantage of high scalability and flexibility.
