Reliability-based data-puncturing hybrid ARQ scheme with LDPC Codes
We propose an improved data-puncturing hybrid-ARQ scheme for Low-Density Parity-Check (LDPC) codes based on codeword reliability. Incremental redundancy is generated from punctured versions of the original data using the same encoder/decoder pair. Retransmission packet sizes are determined adaptively according to the reliability level of the decoded data. We conduct detailed simulation experiments and compare the proposed scheme with RB-HARQ and DP-HARQ approaches. The RB-DP-HARQ scheme reduces the retransmission times and the feedback channel traffic for NACK signaling with negligible overhead.
