Abstract :
The incremental redundancy hybrid ARQ (IR-HARQ) schemes based on finite-length LDPC codes are considered in this paper. The transmission is assumed to take place over time varying binary erasure channels, such as mobile wireless channels at the applications layer for instance. Also, the iterative decoding is supposed. Two following issues are addressed: a) establishment of transmission rules for the m-th transmission after m-1 unsuccessful ones; b) approximation of the throughput and delay performance which would be accurate for finite codelengths, down to several hundreds of bits.
