手机定位中基于TDOA技术的fang算法的仿真(TDOA mobile location technology based on the simulation algorithm fang)

This code is about ricker of seismic data.

天线方向图的波达方向，用于描述回波的方向图1，可以用于初学者学习使用(the antenna dir)

说明：  将小波变换应用于信号消噪,去除冗余分量后，提取信号主要特征(the wavelet can be applied to the signal denoise and feature extraction)

此为智能技术中ICA的代码，快速IcA的代码(This is smart technology ICA' s code, the code quickly IcA)

linear time－frequency toolbox(linear time-frequency toolbox)

In this simulation, a 2 x 2 MIMO system with BPSK modulation is used. Then, the algorithm of V(BLAST is implemented. After that, weight vector is produced using ZF, MMSE and ML detectors. Finally, the BER performance is plotted. A flat fading Rayleigh channel is assumed in this simulation.)

说明：  matlab使用垂直Sobel算子，自动选择阈值 [VSFAT Threshold]=edge(f, sobel , vertical ) 边缘探测 figure,imshow(f),title( 原始图像 ), 显示原始图像 figure,imshow(VSFAT),title( 垂直图像边缘检测 ) 显示边缘探测图像 使用水平和垂直Sobel算子，自动选择阈值 SFST=edge(f, sobel ,2) figure,imshow(SFST),title( 水平和垂直图像边缘检测 ) 显示边缘探测图像 使用指定45度角 Sobel算子滤波器，指定阈值 s45=[-2 -1 0 -1 0 1 0 1 2] SFST45=imfilter(f,s45, replicate ) SFST45=SFST45>=2 figure,imshow(SFST45),title( 45度角图像边缘检测 ) 显示边缘探测图像 (matlab I=rgb2gray(I0) J0=double(I) [VSFAT Threshold]=edge(f, sobel , vertical ) figure,imshow(f),title figure,imshow(VSFAT),title)

说明：  实现对频谱泄露造成的频率谱分析误差，此程序基于MATLAB软件 (To realize the frequency spectrum leakage caused by spectral analysis of error, this program based on MATLAB software)

说明：  《统计信号处理基础 估计与检测理论》，该书本书是一部经典的有关统计信号处理的权威著作。全书分为两卷，分别讲解了统计信号处理基础的估计理论和检测理论。(&quot Statistical signal processing based estimation and detection theory&quot , the book This book is a classic authority on statistical signal processing work. The book is divided into two volumes, respectively, to explain the basis of statistical signal processing, estimation theory and detection theory.)
