PERFORMANCE ANALYSIS OF A HYBRID ERROR CONTROL SCHEME FOR WIRELESS ATM SYSTEMS OVER BURSTY CHANNELS

摘要

摘要: 本文提出了一種適用于無線ATM系統(tǒng)的混合糾錯(cuò)方案:用RS碼保護(hù)話音信號(hào),用截短RS/混合Ⅱ型ARQ保護(hù)圖像和數(shù)據(jù)。文中分析和仿真了這一混合糾錯(cuò)方案在突發(fā)信道上的性能。結(jié)果表明,利用RS碼強(qiáng)的糾錯(cuò)能力,通過有限次的重傳就可獲得低的信元丟失率和傳輸時(shí)延。

Abstract: This paper proposes a hybrid error control scheme suitable for wireless ATM systems, that is, voice telephone is protected by pure RS code, video and data are protected by truncated RS/Type II hybrid ARQ protocol. The performance of this hybrid error control scheme over bursty channels is analyzed and simulated. It is found that, by restricting numbers of retransmission, low transmission delay and cell loss rate can be obtained.
