N2 - Rate-compatible code is a typical way to achieve high forward error correction (ARQ/FEC) systems in packet data transmission. This paper focuses on the construction of efficient rate-compatible low density parity check (RC-LDPC) codes in a flexible way. A special technique to get rate compatible LDPC codes called extending without code-rate threshold is presented in comparison to the results in [6] with code-rate threshold. Based on the improved scheme, a type-II hybrid ARQ scheme is presented in the paper, which is greatly flexible and results in good performance. The throughput performances of different full incremental redundancy (FIR) schemes depend on the length of retransmitted incremental redundancy (IR) substantially. Furthermore, performance comparison between full incremental redundancy (FIR) based on this rate-compatible structure and chase combing (CC) protocols has been investigated.
