A degree distribution design method of Low-Density Parity-Check Accumulate (LDPCA) codes [6] is proposed for rate-compatible asymmetric Slepian-Wolf coding (SWC) of correlated binary memoryless sources. The degree distribution is designed by seeking the simultaneous optimum at the lowest and the highest compression rates of the specified range with density evolution algorithm. The experimental results show that the coding efficiency of codes constructed with the designed degree distribution is close to the Slepian-Wolf limit over the entire target range and better than all other reported results of the rate-compatible asymmetric SWC.
