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: 本源码包参考英国Southampton大学Robert G. Maunder教授2008年的EXIT charts开源demo，给出了通用(分量码多项式可自定义)并行级联Turbo码的EXIT charts的作图源码。同时可完成迭代轨线、BER等值线的绘制等工作。
由于对于码块长较大的情形仿真需要较长时间，源码包也给出了部分分量码多项式的仿真结果，可直接用于绘图。
源码包还给出了最经典的S.Ten Brink介绍EXIT charts基本原理的参考文献，以及本人对通信系统中迭代译码过程分析技术综述的小论文，希望对大家有所帮助。-This source package comes after Professor Robert G. Maunder s open source demo about EXIT charts in 2008 from University Southampton, UK. It is designed for universal (constituent code generation polynomial can be customized) Parallel
Concatenated Turbo Code EXIT charts. The iterative trajectories and BER contour drawing is also completed in this package. Since the long block case costs a lot of simulation time, some simulation results are included in the package. We also give the most classical introduction to the basic principles of EXIT charts from S. Ten Brink, as well as a document about analysis technologies for iterative decoding process in communication systems. Hope this will help. 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
Can be directly run turbo_main.m or LogMAP.m, wait a moment to the simulation results can be observed Platform: |
