Turbo codes represent the new code structures, which consist of pccc ( parallel serially convolutional code ) and sccc ( serially concatenated convolutional code ). in this paper, the background of turbo codes are firstly introduced, which includes the base principle of error correction code 、 block code and convolutional code ; the principle of turbo code and the iterative decoding is secondly expanded ; the key decoding algorithm : a revised map algorithm and iterative decoding theory are detailed ; then, a new turbo code structure : hccc ( hybrid concatenated convolutional code ) is presented, and the capacity of this code method is analyzed, the average capacity upper bound is derived ; at last, this code is simulated on awgn ( additive white gaussian noise ) channel and rayleigh fading channel
本文首先介紹了turbo碼的背景知識,包括差錯控制的基本原理、分組碼和卷積碼;然後闡述了turbo碼的基本原理,包括turbo編譯碼器結構及迭代譯碼原理;較為詳細地描述了關鍵的譯碼演算法: ?種改進的最大后驗概率( map )譯碼演算法及迭代譯碼演算法;提出了一種新的turbo碼結構:混合turbo碼(混合級聯卷積碼) ;並用編碼性能聯合界分析方法對混合turbo碼進行了性能分析,得出了其平均性能上界;並在高斯白噪聲通道和瑞利衰落通道上分別作了一些應用研究及計算機模擬實驗。An important parameter evaluating error control systems is the undetected error probability of the used codes that is studied in theoretical analysis and computer simulation
評價差錯控制系統性能的一個重要指標是所用碼的不可檢錯誤概率。本文從理論分析和計算機模擬兩方面研究分組碼的不可檢錯誤概率。
