Description: S－DES加密算法输入为一个8位的明文组和一个10位的密钥，输出为8位的密文组，解密算法的输入则是一个8位的密文组和一个10位的密钥，输出位8位的明文组。解密过程是加密的逆。程序使用：读入一个文档文件，对其内容加密，输入密钥和选定存放生成密文的目录，点加密；解密操作与加密相似。-S-DES encryption algorithm for the importation of an eight expressly group and a 10 Key, Output for the eight-man group of close, decryption algorithm input is a secret eight-man group and one of the ten key, Output-8 group of expressly. Encryption and decryption is the inverse. Procedure : Reading into a document file, its content encryption, and the importation of selected key storage generating ciphertext directory, point encryption; Encryption and decryption operations similar.

Description: 程序是在不同信噪比情况下两跳协作通信系统分别采用AAF和DAF协议时接收端的误码率仿真主函数twohop.m以及一些子函数,假设信道时瑞利信道。S_R\R_D\S_D的传输距离是1米，调制方式是BPSK，信噪比在-15dB-15dB,接收端合并方式为ERC,迭代次数为1000(The program simulates the BER of the main function twohop. m and some sub-functions at the receiver when the two-hop cooperative communication systems adopt AAF and DAF protocols respectively under different signal-to-noise ratios, assuming the Rayleigh channel. The transmission distance of S_RRDS_D is 1 m, the modulation mode is BPSK, the signal-to-noise ratio is -15 dB-15 dB, the receiver combination mode is ERC, and the number of iterations is 1000.)
