A framework for iterative joint source-channel decoding of JPEG2000 codestreams is presented in this paper. At the encoder, JPEG2000 is used to perform source coding with certain error resilience (ER) modes, and LDPC codes are used to perform channel coding. During decoding, the source decoder uses the ER modes to identify corrupt sections of the codestream and provides this information to the channel decoder. The decoding is carried out jointly in an iterative fashion. Our results indicate that the proposed method improves the convergence rate as well as the overall system performance.
