Description: 现在广义的Turbo码是指采用级联或乘积编码方法并利用迭代译码方法的编译码方案。迭代译码的基本思想是将一个的复杂的长的译码步骤分解为多个相对简单的迭代译码步骤而且在迭代译码步骤之间信息概率的转移或者是软信息的传递确保几乎没有信息损失。
根据其成员码和级联的方法的不同，Turbo码的分类 .本设计论文提供了Turbo码matlab代码以及界面设计（版权所有，仅供参考！）
-now generalized Turbo code refers to the use of the product or cascade method of coding and decoding using iterative methods compiler program code. Iterative decoding the basic idea is a long and complex decoding steps split into a number of relatively simple steps iterative decoding and the iterative decoding steps probability of information between the transfer or soft ensure that the transfer of information almost no information loss. According to its members code and the cascade of different, Turbo code classifications. This paper provides a design Turbo Codes Matlab code and interface design (version All right, for reference purposes only!) Platform: |

Description: 课程设计两个程序：一：数据帧（程序每帧设置为400bit)在有扰信道传输时，采用Turbo码进行编译码。并仿真Log-MAP译码算法在不同迭代次数下的性能。
二：实现有扰信道中，不同信噪比下，采用MAP译码算法的Turbo码的性能。
以上各主程序均有做比较详细的程序注释
可直接运行turbo_main.m或LogMAP.m，稍等片刻即可观察到仿真结果
-two programs of Curriculum design : a: Data frames (each frame is setted to 400bit per frame) ,under a interferent channel transmission uses Turbo codes and decodes. including simulation of Log-MAP decoding algorithm performance under different number of its iterations.
2: To achieve the simulate the performance of MAP decoding algorithm for Turbo code,with different SNR that is decided by interferent channel.
Above the main program have to do a more detailed program notes
