Successive Wyner-Ziv Coding for the Binary CEO Problem under Logarithmic Loss

The $L$ -link binary Chief Executive Officer (CEO) problem under logarithmic loss is investigated in this paper. A quantization splitting technique is applied to convert the problem under consideration to a $(2L-1)$ -step successive Wyner-Ziv (WZ) problem, for which a practical coding scheme is proposed. In the proposed scheme, Low—Density Generator—Matrix (LDGM) codes are used for binary quantization while Low—Density Parity—Check (LDPC) codes are used for syndrome generation; the decoder performs successive decoding based on the received syndromes and produces a soft reconstruction of the remote source. The simulation results indicate that the rate—distortion performance of the proposed scheme can approach the theoretical inner bound based on binary—symmetric test—channel models.
