OFDM

说明：  一些时反的例程和其他代码，mat文件是信道信息(The Mat file is the channel information. There are some examples of the Time Reverse and communication system.)

本程序的性能已经达到较高水平，用于特征降维，特征融合，相关分析等,对于初学者具有参考意义。( The performance of the program has reached a high level, For feature reduction, feature fusion, correlation analysis, For beginners with a reference value.)

1、 利用哈夫曼编码进行通信可以大大提高信道利用率，缩小信息传递时间，降低传输成本(1, the use of Huffman coding can be greatly improved communication channel utilization, reducing the information transmission, reduce transmission costs)

非均匀天线组阵SUMPLE权值信噪比及信号合成性能分析(Non-uniform antenna arraying SUMPLE weights SNR performance analysis and signal synthesis)

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.)

用matlab/simulink中s函数实现VCO(S function implementation with VCO in simulink)

说明：  UR旋转矢量转化，转化为RPY坐标，更加适合编程，非常靠谱(UR Rotation Vector Conversion)
