The Study of Low-Delay Incremental Redundancy Hybrid ARQ Schemes in Adaptive Modulation System

  • 摘要: 冗余遞增混合ARQ能提供較高的數(shù)據(jù)通過率，但也帶來了較大的傳輸時(shí)延。該文提出一種具備低時(shí)延冗余遞增策略的混合ARQ系統(tǒng)并與自適應(yīng)調(diào)制系統(tǒng)相結(jié)合，不但根據(jù)不同的接收信噪比，選取不同的調(diào)制方式，而且還選擇不同的冗余遞增策略。仿真和計(jì)算結(jié)果表明，與采用固定冗余遞增策略的自適應(yīng)調(diào)制混合ARQ系統(tǒng)相比，該系統(tǒng)在保證較高的數(shù)據(jù)通過率的前提下，大大降低了系統(tǒng)傳輸時(shí)延。
    Abstract: The incremental redundancy hybrid ARQ scheme can provide high throughput efficiency. Meanwhile, it also leads to high transmission delay. This paper presents a Low-Delay Incremental Redundancy hybrid ARQ scheme with Adaptive Modulation (AM-LD-IR). It adopts different strategy of incremental redundancy and constellation size according to the received Signal-to-Noise Ratio (SNR). The calculation and simulation results in the paper show, comparing to the ordinary incremental redundancy hybrid ARQ systems with adaptive modulation, the AM-LD-IR system can provide a little higher throughput efficiency and can reduce much transmission delay.
