通过计算机MATLAB仿真分析和研究了维纳滤波器的阶数、信号的噪声方差、随机信号的采样点数、经过维纳滤波的均方误差之间的关系(MATLAB simulation by computer analysis and research of Wiener filter order, the signal of the noise variance, random signal sampling points, after Wiener filter mean square error of the relationship between)

说明：  16单元线阵3单元music算法，估计信号波达方向(Array of 16 units, Unit 3, music algorithm, estimated DOA)

用matlab编写的基于SVD的鲁棒水印程序(prepared using Matlab based on the robust watermark SVD procedures)

this code optimize the parameter of PID controller

说明：  无线通信，软件无线电，SDR的有关程序 很好啊，哥哥最近在研究这些，想做一个软件无线电的接收机啊，可惜，这个该死的网站，不让我下，吐血，哥哥决定贡献自己的东西，让技术不再隔阂(SDR OFDM QPSK ASK )

ofdm在瑞利信道的仿真程序还有snr，ber图形(ofdm simulation program in Rayleigh channel also snr, ber graphics)

压缩包里只有程序没有仿真图">

说明：  里面包含很多MATLAB时频分析的程序，很有用。通过稍微改动就可以应用到其他的地方。(matlab source program)

correlation matching using matlab it is a code used for match correlation a image in matlab software. using this we can a correlate an image.

Advanced correlation filter synthesis algorithms to achieve rotation invariance are described. We use a specified form for the filter as the rotation invariance constraint and derive a general closed-form solution for a multiclass rotation-invariant filter that can recognize a number of different objects. By requiring the filter to minimize the average correlation plane energy, we produce a multiclass rotation invariant (RI) RI-MACE filter, which controls correlation plane sidelobes and improves discrimination against false targets. To improve noise performance, we require the filter to minimize a weighted sum of correlation plane signal and noise energy. Initial test results of all filters are provided
