本人长期从事matlab中simulink在无线通信上的仿真（通信抗干扰国家重点实验室），此Turbo迭代译码程序是我见过的最经典的链路，过程非常的清晰，尤其迭代译码部分巧妙的利用降速率用最简单的结构实现了复杂的迭代过程，值得同行学习，必有极大收获！(err)

从互联网上搜索并下载至少3个英文原版TXT格式小说，设计程序统计每个小说中26个英文出现的次数，所占百分比。 根据程序输出结果分析莫尔斯码对各英文字母设计的编码的合理性。(Search and download from the Internet at least 3 TXT format, original English novel, the novel design process statistics for each of 26 English and the number of occurrences percentage. According to the procedure output of Morse code letters on the design of the code is reasonable.)

ITU-R SM.1134-1建议书 陆地移动业务中互调干扰的计算. 本建议书为计算最多三种互调干扰提供了依据，接收机输出端出现的这种互调干扰，是接收机幅度响应的非线性在接收机输入端产生的强烈无用信号引起的。(Intermodulation interference calculations. ITU-R SM.1134-1 proposal in the land mobile service this proposal is calculated up to three intermodulation interference to provide a basis for this receiver output intermodulation interference, receiver nonlinear amplitude response due to strong unwanted signals at the receiver input.)

ES is a symmetric block cipher. The same key is used to encrypt and decrypt the message. The plain text and the cipher text are the same size. The Aes algorithm works as follows: Convert to state array: This step consists of conversion on the matrix onto a state array operating with the sbox. Transformations (and their inverses) AddRoundKey: Computing the round key for each round. SubBytes: Substituting by bytes from Sbox. ShiftRows: Shifting of rows. MixColumns: Exor operation on columns. Key Expansion: Expanding the key to be used on next round.
