基于校正子的第一類混合ARQ及其性能分析

Syndrome-Based Type-I Hybrid ARQ and Its Performance Analysis

  • 摘要: 基于校正子的計算提出了一種第一類混合ARQ (HARQ) 方案，該HARQ采用Reed-Solomon (RS)碼作為糾錯子系統(tǒng)，將檢錯功能巧妙融于譯碼過程中。對系統(tǒng)誤比特率和吞吐量的分析與仿真表明，短碼宜采用前向校正子結構，長碼宜采用后向校正子結構，而系統(tǒng)的吞吐量與可靠性之間的最佳折衷，可以通過選擇恰當?shù)淖畲笾貍鞔螖?shù)實現(xiàn)。
    Abstract: A syndrome-based type-I Hybrid ARQ (HARQ) is proposed, where Reed-Solomon code is selected to be the FEC subsystem and the error-detection function is embedded ably in the decoding process. Analytical and simulation results of Bit Error Rate (BER) and throughput efficiency of the system show that syndrome-ahead and syndrome-behind structures are suited to short codes and long codes, respectively. By choosing the maximum of retransmission times, a perfect tradeoff can be obtained between the throughput efficiency and the reliability of the system.
