渦輪碼自從由法國的Berrou et al提出之後,激起通信界熱烈的響應,競相投入渦輪碼相關研究,試圖找出最佳的編解碼方案,渦輪碼的提出被視為眾多通道編碼理論中的新標竿,渦輪碼因具備接近Shannon理論極限的譯碼性能,被評價為現有眾多通道編碼理論中最優的,渦輪碼因具備優越的錯誤更正能力,所以廣泛應用在無線通信系統並已被第三代個人行動通信系統採用為通道編碼方式之一。本論文對應用在第三代個人行動通信系統的渦輪碼進行性能分析,並對渦輪碼的交錯器進行了深入探討。
The introduction of Turbo codes, by Berrou et al. has generated interest in devising high performances coding schemes. The present of it is viewed as landmark in the development of the theory of channel coding. Turbo code has obtained the performance near to Shannon theoretic limit. The performance of Turbo code is the best one in all presented coding methods. With the excellent of error correction capability, Turbo code has been widely used in wireless communication system and adapted as one of 3G channel coding standards. In this paper, the performance analysis of Turbo codes in the 3G systems are discussed. Finally the interleaving technologies for Turbo codes in 3G application are further studied.
