bit error rate of bpsk modulation

用matlab做的趣味日历 感觉还不错(Matlab to do with feeling good fun calendar)

The code performs the Neighblock wavelet thresholding method for image denoising

说明：  该程序为用MATLAB编写的一个小波变换工具箱，跟之前的toolbox1程序包实现的功能有所不同(The program prepared for the use of a MATLAB toolbox wavelet transform with the package before toolbox1 function to achieve different)

考虑载波的qpsk信号在瑞利信道上的仿真(consider Carrier qpsk Rayleigh channel signal simulation)

实现一个LCC滤波 电感Lr，电感电阻R，与电感串联的电容Cr，输出并联电容Co(achieve a filter inductor Lr, inductance and resistance R, the series inductor and capacitor Cr, Parallel output capacitance Co.)

通过抖动编码，将图像转换成灰度图像；用matlab实现(convert the image to gray level image by using the jitter code method)

pca lda kpca klda lpp matlab 特征降为方法，对于新手比较有用。(pca lda kpca klda lpp matlab code for dimension reduction. these are very useful for new researchers.)

数字水印实现技术,实现图像的水印防伪处理，灵活实现水印嵌入(image watermark)

说明：  使用HOPfield神经网络求解参数线性约束规划，此代码为原创，可直接运行。(Use HOPfield Neural networks for solving parametric linear constrained programming, the code for the original, can be directly run.)
