short forie tranform compute

turbo编码和三种解码方法的matlab程序(turbo code and decode)

说明：  雷达信号相关内容，已打包成函数，bpsk，fsk，lfm等(Radar signal related content, packed into functions, BPSK, FSK, LFM, etc)

利用Matlab实现光学系统光线追迹功能(Ray tracing of optical system with matlab)

channel create and simulation in OFDM system

说明：  分析信号的系统响应的实验代码，附有详细的实验说明和源代码，并对实验现象进行解释(Analysis of the signal system in response to the experimental code, with detailed experimental descriptions and source code, and to explain experimental phenomena)

信息论中变长编码的香农编码程序，大家可以互相学习(In the information theory of shannon length coding encoding process, we can learn from each other)

说明：  一个高阶系统转换为状态空间的matlab算法，附有原理(A high-end system into a state space matlab algorithm, with a principle)

仿真了用于MIMO雷达的OFDM Chirp波形的自相关函数和互相关函数，便于进一步优化OFDM Chirp波形，使互相关和自相关性能接近正交波形的性能，从而提高雷达目标检测性能。因为匹配滤波相当于一个互相关器。附有所仿真波形的参考文献，波形设计见本人之前上传的文件(this matlab program simulate the correlation function of ofdm chirp waveform,so that reader can optimizing design new ofdm chirp waveform.from the simulation results we see that the correlation performance are not well enough,so we have to optimize the ofdm chirp.there is reference of my simulation.)

Recusive Drawing for a star, it depends on the angle between the edged of the star, also the user sets to witch level he wants the star to be recusivly drawn.
