排序統計軟性決定解碼應用於混合型自動要求重傳機制之效能評估與可適性研究

Performance Evaluation of Ordered-Statistics Soft Decision Decoding for Hybrid ARQ Protocols and Adaptive Error Control

指導教授 : 張進福

摘要


隨著無線通訊技術應用的快速發展,在無線通道上的資料傳輸也變得日益重要,由於無線通道受到多種不同的干擾,與有線通道相較之下會有較高的錯誤發生機率。為了因應這種情形,我們需要研究較以往更為有效的錯誤控制機制,以確保通訊的服務品質(QoS)。 本論文主要是結合錯誤更正碼的軟性解碼研究,提出一些方法改善傳統的錯誤控制機制以增進其系統效能;更進一步則利用通道狀況資訊,設計一種可適性錯誤控制機制,使得傳送端產生的資訊能以最有效率的方式被傳輸到接收端。在這裡我們關心的是系統的輸出率(Throughput)以及可靠度(Reliability)上的表現。

For data transmission on wireless channel, because of the higher error probability, we need some more efficiency error control protocols to make sure the QoS of communication. We use soft-decision error correcting codes to improve the system performance of traditional error control mechanism; further more, we design an adaptive error control mechanism using channel condition. We aims the system performance of Throughput and Reliability.
