Based on the conception of majority voting, a hybrid ARQ scheme for binary linear block codes over AWGNchannel is presented. At each transmission, the received word is kept in memory buffers if errors are detected. If thereare still errors after a number of transmissions, the re-transmission stops to improve the throughput efficiency. From thereceived words, the decoding process of proposed hybrid ARQ first determines each bit as 1 or 0 based on the majorityof the corresponding bits in the received words. The word resulting from voting is then decoded by algebraic decoder asthe output code word. Simulation results show that the proposed hybrid ARQ scheme outperforms ARQ scheme in botherror-correcting performance and throughput efficiency, particularly under low SNR. Additionally, a criterion in termsof throughput and coding gain is proposed for overall evaluation of hybrid ARQ schemes compared to that of ARQscheme. Comparisons between plurality-based hybrid ARQ and majority-based hybrid ARQ are also made on the basisof proposed hybrid coding gain. |
