Conferences: Progressive encoding with non-linear source codes for compression of low-entropy sources
Ramirez Javega, M. Lamarca Orozco and J. Garcia-Frias


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.
