摘要
信道编码是数字通信系统中的重要组成部分,他是保证信号可靠传输的一种重要方式。卷积码以其优越的性能被广泛使用在数字通信系统中。(2,1,7)卷积编码已经是国际卫星通信的标准。介绍了卷积码的特点以及卷积码的编码、译码原理,主要讨论了卷积码的Viterbi译码及其算法,最后通过Matlab仿真,对卷积码的性能进行了理论分析和实验仿真。
Channel coding is the important part in the digital communication system. It is also a way to ensure the reliability of the transmission in this system. Convolution code is widely used in the digital communication system by the ascendant performance. （2,1,7）convolution code is the standard in the international satellite communication. In this article,the characteristics and the principles of convolution coding and decoding are introduced. It mainly discusses Viterbi decoding algorithm of convolution code. In the end,the performance of convolution code is analyzed and simulated based on Matlab.
