GaussianSource Coding Based on P-LDPC Code

A lossy source coding system based on the protograph low-density parity-check (P-LDPC) code is proposed for Gaussian source compression. In the proposed system, the conventional belief propagation (BP) algorithm is modified to be a concatenated BP-inverse BP (BP-[Formula Omitted]BP) for encoding and...
