Zhibin Sun, Mingkai Shao, Jun Chen, Kon Max Wong, Xiaolin Wu · IEEE Transactions on Communications · 2010
It is shown that binary low-density generator matrix codes can achieve the rate-distortion bound of discrete memoryless sources with general distortion measure via multilevel quantization. A practical encoding scheme based on the survey-propagation algorithm is proposed. The effectiveness of the proposed scheme is verified through simulation.
