非常好的资料,希望大家有用,GA遗传算法的Matlab程序原理资料.(Very good information, I hope everyone useful, GA genetic algorithm Matlab program theory information.)

该代码实现了以2为因子的图像升采样和降采样功能。 降采样包括使用平滑滤波器(with using the averaging filter)和不使用平滑滤波器(without using the averaging filter)两种方法。 升采样包括像素点直接复制(pixel replication method)和线性插值(bilinear interpolatoin method)两种方法。 降采样方法和升采样方法共有4种组合。程序运行后，给出了一个原始图片和四个结果图片。 图片1.原始图片。 图片2.平滑滤波器降采样&像素点直接复制升采样。 图片3.平滑滤波器降采样&线性插值升采样。 图片4.不使用平滑滤波器降采样&像素点直接复制升采样。 图片5.不使用平滑滤波器降采样&线性插值升采样。 (The code to achieve a 2-factor image upsampling and downsampling function. Down-sampling (with using the averaging filter) and do not use smoothing filter (without using the averaging filter) are two ways to use the smoothing filter. Upsampling including the pixels copied directly (pixel replication method) and linear interpolation (bilinear interpolatoin method) two methods. Down-sampling method and liters a total of four combinations of sampling methods. The program is running, it shows a picture of an original picture and four results. Picture 1 original picture. Photo 2. Smoothing filter downsampling & the pixel directly copied liter sample. Photo 3. Smoothing filter downsampling & the linear interpolation liter sampling. Picture 4.

程序主要包含幂级数展开逼近余弦及在同一坐标下显示多个曲线。压缩包中还包含相关的参考资料。(Program mainly includes power series expansion approximation cosine and displayed in the same coordinate multiple curves. Compressed package also contains the associated reference materials.)

用于特征降维，特征融合，相关分析等,数值分析的EULER法，音频信号通过LM386放大。( For feature reduction, feature fusion, correlation analysis, EULER numerical analysis method, LM386 audio signal amplification.)

说明：  RS的编码以及迭代译码，是【7,3 5】的RS码，希望对大家有帮助(it can work well~hope can help you)

Simple simulink model BPSK

利用LS_MSE实现信道估计（matlab源代码）(channel estimation using LS_MSE)

说明：  产生一个chirp信号，给出时域及频域特性。利用匹配滤波器进行滤波。如果有延时也能正确滤波。(Generate a chirp signal, given the time domain and frequency domain characteristics. Filtering using matched filter. If there is delay filter can correct.)
