  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.
