QPSK modulation with awgn channel

matlab simulink bidirectional converter

802.11a物理层仿真代码，matlab(802.11a physical layer simulation code, matlab)

this code is to learn about MATLAB

matlab做的，关于滚动轴承振动信号故障诊断很重要的数据库，做机器学习的朋友可以看看啊！(Matlab do, on the rolling bearing vibration signal fault diagnosis is very important , machine learning friends can see ah!)

采用蚁群算法检测图像边缘 This a demo program of image edge detection using ant colony, based on the paper, "An Ant Colony Optimization Algorithm For Image Edge Detection," IEEE Congress on Evolutionary Computation (CEC), pp. 751-756, Hongkong, Jun. 2008. (Ant colony algorithm using edge detection This a demo program of image edge detection using ant colony, based on the paper, )

说明：  模拟退火matlab源码，学习模拟退火很好的例子(Simulated annealing matlab source, learning good example of simulated annealing)

求任意带宽的低通、高通、带通高斯白噪声的自相关函数，自协方差函数和功率谱密度函数。(Seeking any bandwidth low pass, high pass, band pass Gaussian white noise autocorrelation function, autocovariance function and power spectral density function.)

极化雷达图像sigma0计算程序，给定极化雷达图像后，可以计算获得不同极化组合的雷达图像(Given a polarimetric image, the code synthesizes the radar image for any specified transmit and receive polarization combination.)

这是《Numerical Methods with MATLAB: Implementation and Application》一书的配书程序（Matlab）(matlab code for "Numerical Methods with MATLAB: Implementation and Application")
