viterbi
- 卷积码的译码方法主要有两种：代数译码和概率译码。代数译码是根据卷积码的本身编码结构进行译码，译码时不考虑信道的统计特性。概率译码在计算时要考虑信道的统计特性。典型的算法如：最大似然译码、Viterbi译码、-Convolutional Decoding by two major ways : Decoding algebra, probability and decoding. Decoding is based on algebraic Convolutional Codes itself c
hammming
- 该程序实现了高斯信道传输信息中未编码时和采用汉明【7，4，3】码时不同误码率的统计，得到汉明74码的性能。-realized by the Gauss channel to transmit information not to code and the use of Hamming codes -- [7,4,3 different error rate statistics, to be prescribed 74-yard performance.
实验5
- 哈夫曼编码/译码 背景介绍： 利用哈夫曼编码进行通信可以大大提高信道利用率，缩短信息传输时间，降低传输成本。但是，这要求这发送端通过一个编码系统对待传数据预先编码，在发送端将传来的数据进行译码（复原）。对于双工信道。每端都需要一个完整的编译码系统。本程序将为这样的信息收发站写一个哈夫曼的编译码系统。 哈夫曼编码/译码： 程序运行步骤： １、建立哈夫曼树，从键盘输入字符集大小，字符以及频度。 ２、对字符进行编码，输出编码结果，分单个句子和整个句子输出，编码导入
