LDPC code ensembles for incremental redundancy hybrid ARQ
Nedeljko Varnica, Emina Soljanin, Philip Whiting · 2005
An LDPC code based hybrid ARQ scheme with random transmission assignments is analyzed. The spectrum properties of LDPC code ensembles that are necessary for this analysis are derived. Very good estimates of maximum-likelihood decoding error rates after each transmission are provided. The results are tested on practical code examples by simulation
