离散无记忆信道的容量价值函数和信道编码定理。 - There are many decoding schemes for convolutional code , such as sequence decoding algorithm , fano algorithm , viterbi algorithm . but in fact , what ' s used widely is viterbi decoding algorithm . the viterbi decoding algorithm , proposed in 1967 by viterbi , is a decoding process for convolutional codes in memory - less channel , which takes full advantage of convolutional codes . since viterbi algorithm is proposed , it has obtained rapid development whether in theoretics or in practice and been applied to all kinds of data transmission systems , especially to digital wireless communications and deep space communications
卷积码的译码算法方案有很多，如序列译码算法、 fano算法、 viterbi算法，但是真正大规模应用的还是viterbi算法。 viterbi译码算法是1967年viterbi提出的，它是一种对无记忆信道卷积码进行译码的算法。它充分发挥了卷积码的特点，因而自viterbi算法提出以来，无论在理论上还是在实践上都得到了极其迅速的发展，并广泛的应用于各种数据传输系统，特别是无线通信和卫星通信系统中。 - This paper can put into four parts ? this first part is the description and theoretical analyses of source coding , which focus on the research of optimizing equal quantization ? the second part presents the theoretical description of joint channel - source coding , which focus on the research of combined channel - source coding o the third part is about the application of combined channel - source coding to two different channel models , binary symmetric channel and cdma channel o in this part , two different coding designs are given according to different characters of these two channels ? and the last part is the description of simulation of combined channel - source coding ? most of my work are about two parts , one is to find the most appropriate quantization steps and centroid points of separate channel - source coding , another is to simulate the combined channel - source coding ? comparing the simulation results of separate channel - source coding and combined channel - source coding , the characters of joint channel - source coding are given
