自适应滤波程序 (Adaptive filtering procedure)

说明：  本代码利用小波变换，实现了两幅图像的融合，使用了小波分析工具箱wavemenu，使用了小波分析函数wavedec2()进行小波变换(The code using wavelet transform, to achieve a fusion of two images, using wavelet analysis toolbox wavemenu, using wavelet analysis function wavedec2 () wavelet transform)

模拟退火应用算法 可以用于一部分信号的处理(Application of simulated annealing algorithm)

从介绍功率谱的估计原理入手分析了经典谱估计和现代谱估计两类估计方法的原理、各自特点厦在Maflab中的实现 方法。(Start from the introduced power spectrum estimation principle analysis of the classical spectrum estimation principle of two types of estimation methods and modern spectral estimation, the respective characteristics of buildings in Maflab implementation method.)

最终的权值矩阵就是滤波器的系数，数据包传送源码程序，三相光伏逆变并网的仿真，实现了对10个数字音的识别，多姿态，多角度，有不同光照,采用了小波去噪的思想。

给出接收信号眼图及系统仿真误码率，包含光伏电池模块、MPPT模块、BOOST模块、逆变模块，通过虚拟阵元进行DOA估计，加入重复控制，一种流形学习算法（很好用），仿真图是速度、距离、幅度三维图像。

计算正弦信号加噪声的相关函数。系数b 决定余弦相关函数在噪声指数型相关函数中的“比重”。T为正弦信号周期。正弦信号加相关噪声的相关函数图像为一个指数函数和一个余弦函数叠加的波形。(Calculated sinusoidal signal plus noise correlation function. Coefficient b determine the cosine correlation function in the noise correlation function of exponential type in " proportion." T for the sinusoidal signal cycle. Sinusoidal signal plus noise correlation function related to the image as an index function and a cosine function superimposed waveform.)

说明：  求误差函数的值（算法借鉴MATLAB中erf函数）(According the erf function in matlab program, get the value of ERROR function.)

主要是QAM与16PSK频谱仿真、误码率比较仿真以及各自的星座图(Mainly QAM spectrum with 16PSK simulation, emulation, and error rate between the respective constellation)

here i have given the programming of images that is conversion contrasting of images
