Progressive encoding with non-linear source codes for compression of low-entropy sources

Abstract: Abstract-. We propose a novel scheme for source coding of non-uniform memoryless binary sources based on progressively encoding the input sequence with non-linear encoders. At each stage, a number of source bits is perfectly recovered, and these bits are thus not encoded in the next stage. The last stage consists of an LDPC code acting as a source encoder over the bits that have not been recovered in the previous stages.

“…Due to this, for GT the equivalent message passing algorithm for LDPrC codes is obtained by swapping all zeros by ones and the ones by zeros in vector x 0 and y 0 , which translated to swap all signs of equations (2.11) in section 2.2.2. Alternatively we can also employ the erasure decoding (ED), an algorithm that we proposed in [116].…”
