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: |

Description: Matlab simulation for drawing the BER plot of the LTE turbo code, using either the BCJR algorithm or the fully-parallel algorithm.
Copyright (C) 2013 Robert G. Maunder
The simulation can be started by running the main.m script. This can be modified to either the BCJR algorithm or the fully-parallel algorithm, as well as to the frame length N. As the simulation proceeds, it will gradually plot the BER that can be achieved using various number of decoding iterations, as selected in main.m. A greater number of decoding iterations will give a lower BER. The script main.m can also be modified to make the BER plots smoother and reach lower BERs, at the cost of making the simulation run slower.-Matlab simulation for drawing the BER plot of the LTE turbo code, using either the BCJR algorithm or the fully-parallel algorithm.
