matlab---DEA

Matlab基本知识，matlab学习入门,希望对大家有用。(this article of Matlab is useful to you .good good study, day day up .Hope you have a good day .)

详细的介绍了matlab仿真的原理与技术，具有重要的意义(Detailed description of the matlab simulation theory and technology of great significance)

说明：  本次设计是对GSM TCH/FS信道进行编码设计及性能仿真,仿真通信系统包括内外编码器、交织重排器、加性/突发和混合干扰信道、去交织反重排器、内外译码器，模拟了信息从信源到信宿的全过程； 在高斯噪声、突发干扰或混合信道及瑞利信道下测试每个步骤对误码率和系统性能的影响，通过数字及图形的比较，得出通信系统中各个模块的作用。另外，在GSM TCH/FS 的基础上建立GSM TCH/EFS 信道，对相应的信道环境进行仿真，得出误码率分析。 (This design is the GSM TCH/FS channel encoded design and performance simulation, simulation communication system, including internal and external encoder, interleaving rearrangement device, the additive/burst and mixed interference channel, to the cutting device against rearrangement, internal and external decoding and analog information from the source to the destination of the whole process in Gaussian noise, sudden disruption or mixing channel and Rayleigh channel to test each step of the bit error rate and system performance, by comparison of digital and graphic obtained communication systems the role of each module. In addition, GSM TCH/FS based on the established GSM TCH/EFS channel, the corresponding channel environment simulation, the error rate analysis)
