通过高斯函数导数检测图像边缘，实质是方向可调小波变换检测图像边缘。(Derivative to detect image edges by Gaussian function, in essence, the steerable wavelet transform to detect image edges.)

本实验要求掌握时域特征分析原理，并利用已学知识，编写程序求解语音信号的短时过零率、短时能量、短时自相关特征，分析实验结果，并能掌握借助时域分析方法所求得的参数分析语音信号的基音周期及共振峰。基于MATLAB的语音信号时域特征分析(In this study, the analysis required to master the principles of time-domain characteristics, and use the learned knowledge to write programs to solve short-time speech signal zero-crossing rate, short-time energy, short-term autocorrelation features, analysis of the experimental results, and can grasp the time domain by means of analytical methods pitch the determined parameter analysis of the speech signal and formant. Based on time-domain characteristics of the speech signal analysis MATLAB)

This is matlab simulink files related MIMO. If u find the ofdm and Mimo, then u can click the 802.11a+2tx2rx files. Thank you
