| Abstract(in English) | Recently, the application of the low density parity check (LDPC) codes to Slepian-Wolf source coding problem is studied, and the sum-product algorithm, that can approximately emulate maximum a posteriori probability (MAP) decoding, is known as the practically efficient decoding scheme for the LDPC codes. The sum-product algorithm uses the probability distribution with estimation error to decode the encoded data. In Slepian-Wolf source coding problem with such decoding scheme, the admissible rate region has not been derived yet. In this paper, we derive an inner bound on the admissible rate region for Slepian-Wolf source coding problem with mismatched decoder and the encoders satisfying some constraints. Furthermore, our inner bound can be achieved by LDPC codes. |
