FRFT
给出了分数阶傅里叶变换的具体实现程序,阶数可调。该程序实现是根据一篇通信学报上的论文做的。同时提供了OFDM系统在不同信道估计技术下的误码率以及多径信道下的性能。对于想研究基于分数阶傅里叶变换的OFDM系统的人有一定帮助。(The codes for fractional fourier transform (frft) and its inverse way are given according to a published paper in Journal of Communication. The power is adjustable. In addition, two programms of OFDM system simulation under different channel estimate technique and multipath are offered. Therefore, such file packet is of use for those who have interests in studying OFDM based on frft)

MSBCS
说明: 在MTLAB环境运行main_msbcsspl.m。该程序的功能是实现图像的稀疏分解并重建图像,采用压缩感知理论,利用小波分析,在小波域分块观测,可以用很少的观测值就能重建原图像。程序包中已经整合了小波包和测试图像,没有多余文件,程序经过亲测并修改,能在MATLAB中直接运行得到很好的结果,速度非常快!(Run main_msbcsspl.m in the MTLAB environment. The function of the program is to decompose and reconstruct the image sparsely. Using compressed sensing theory and wavelet analysis, the original image can be reconstructed with very few observations. Wavelet package and test image have been integrated in the package. There are no redundant files. After testing and modifying the program, it can run directly in MATLAB and get good results. The speed is very fast.)

CDMA系统仿真
说明: CDMA技术的原理是基于扩频技术,即将需传送的具有一定信号带宽信息数据,用一个带宽远大于信号带宽的高速伪随机码进行调制,使原数据信号的带宽被扩展,再经载波调制并发送出去。CDMA系统仿真,初学者(CDMA system simulation)
