Design of Binary LDPCA Codes with Source Revealing Rate-Adaptation
Sangyun Shin, Min Jang, Sang‐Hyo Kim, Byeungwoo Jeon · IEEE Communications Letters · 2012
In this letter, we consider binary low density parity check accumulate (LDPCA) codes with source revealing rate-adaptation for distributed source coding (DSC) applications. We propose an effective algorithm for selecting source symbols to the source revealing. Numerical results demonstrate that the proposed scheme significantly outperforms the conventional LDPCA codes in the high compression rate region in asymmetric DSC systems.
