采用wiener_HOLF方法实现的维纳滤波的过程，对加噪图形采用维纳滤波(wiener_holf method)

说明：  主要介绍了准正交空时分组码，包括ABBA，jafarkhani(Introduced quasi-orthogonal space-time block codes, including ABBA, jafarkhani)

彩色图像批量转换为灰度图像并自动保存，刚刚写好的一个小程序(Batch convert color images to grayscale images and automatically save, just a small program written)

说明：  一维信号BP重构算法，先生成稀疏度为K的稀疏矩阵，再加入高斯白噪声进行算法重构以及质量衡量。(BP signal reconstruction algorithm for one dimensional, Mr. into sparse matrix sparsity of K, then the Gauss white noise and measure the quality of reconstruction algorithm.)

通过布里渊频移的变化和散射功率的变化仿真构建布里渊频移变化量的空间分布和布里渊散射功率变化量的空间分布(Brillouin frequency shift change through changes and scattering power of simulation to build Brillouin frequency shift amount of space Brillouin scattering power distribution and the spatial distribution of the amount of change)

说明：  该程序是一位同学写的，运行该程序需要rtlSDR设备，便宜一点的淘宝不到100元，插上rtlsdr后，配置好matlab环境，能够实现扫描25M-1.75GHz的当地频谱，当然也可以自行修改范围(rtlsdr rx specsweeep 25MHz~175MHz)

说明：  利用压缩包内的5和函数产生PPM调制的UWB信号，信号波形为高斯二阶导函数。重复编码次数，TH码长度范围，波形形成参数alpha等参数均可以改变(use compressed within the five functions to generate PPM and the UWB signal modulation, Waveform second derivative of the Gaussian function. Repeat code number, TH code length, alpha waveform parameters such as formation parameters can be changed)
