摘要：

Distributed source coding (DSC) is a new technology for source compression. In contrast with the traditional source compression methods, DSC achieves low-complexity encoding by transferring complex decorrelation process from the encoder to the decoder, so that it is suitable for friendly up-link serves of low-power devices such as mobile phones. This paper addresses the transmission of DSC bit stream and proposes two kinds of transmission systems, including distributed joint source-channel coding (DJSCC) and distributed separate source-channel coding (DSSCC). And LDPC (Low Density Parity Check) is used in these two systems for the simulation experiments which finally show that DJSCC outperforms DSSCC in practice.
