A hybrid ARQ scheme using RCPT codes and its performances over Rayleigh fading channel

This paper presents an effective hybrid ARQ (automatic repeat request) scheme based on RCPT (rate compatible punctured turbo) codes and CPC (alternate "codeword retransmission" and "parity retransmission" and Chase combining) strategy. The performance of the proposed scheme is investigated over the Rayleigh fading channel, and several existing hybrid ARQ schemes using RCPT codes are compared on both performance and complexity.
