瑞利信道下空时编码下的MATLAB仿真 对两信道下的瑞利传输进行仿真(Rayleigh channel space-time coding under the MATLAB simulation)

this code is a aplication for add gaussian noise in aimage I using a color Image for myjob. it maybe create with a while noise in image It writed in Matlab environment

可利用feko得到回波或根据公式构造回波，基于字典缩放的属性散射中心的参数提取，并重构回波(The echo can be obtained by using FEKO, or the echo can be constructed according to the formula. The parameters of the scattering center of the dictionary are extracted based on the dictionary scaling and the echo is reconstructed.)

此文件包含有四个基于matlab源程序,可直接运行.其说明如下 P0301：数字图像矩阵数据的显示及其傅立叶变换 P0302：二维离散余弦变换的图像压缩 P0303：采用灰度变换的方法增强图像的对比度P0304：直方图均匀化(This file contains four based on the matlab source code can be directly run. Its description is as follows P0301: digital image data display matrix and its Fourier transform P0302: Two-dimensional discrete cosine transform image compression P0303: the use of gray-scale transformation method contrast-enhanced images P0304: Histogram of homogenization)

利用S函数生成空间矢量SVPWM，可用于异步电机、同步电机的Matlab控制仿真的逆变模块(The S function to generate space vector SVPWM, can be used for asynchronous motors, synchronous motor control simulation Matlab inverter module)

Technical Area pattern classification

说明：  对曲线进行拟合，使得最后拟合的数据与元数据的误差最小(The curve fitting, so that the final fitting of the data with the metadata minimum error)

使用于机械最优化设计课程的检索优化方法的最速下降法(Optimized for use in mechanical retri method optimized design courses steepest descent method)

16-QAM matlab program, it can be run(16 QAM Matlab)

说明：  倒谱分析 倒谱分析是指信号短时振幅谱的对数傅里叶反 变换。它具有可近似地分离并提取出频谱包络信息 和细微结构信息的特点(Cepstrum analysis cepstrum analysis is the signal amplitude spectrum on the number of short-time Fourier inverse transform. It has can be approximately isolated and extracted spectral envelope information and fine structural characteristics of information)
