基于小波变换和经验模态分解的大地电磁信号静态效应消除源程序(Based on wavelet transform and empirical mode decomposition of the magnetotelluric signal source to eliminate the static effect of)

是hht中的emd分解，很好用。可以进行经典模态分解，分解出不同的IMF（固有模态函数）(the EMD of Hilbert-huang transform .it can get IMF.)

this is the matlab code by using the music algorithm for finding the direction of arrival of the smart antennas

This demo shows the BER performance of linear, decision feedback (DFE), and maximum likelihood sequence estimation (MLSE) equalizers when operating in a static channel with a deep null. The MLSE equalizer is invoked first with perfect channel knowledge, then with an imperfect, although straightforward, channel estimation algorithm. The BER results are determined through Monte Carlo simulation. The demo shows how to use these equalizers seamlessly across multiple blocks of data, where equalizer state must be maintained between data blocks.

本程序是切比雪夫低通滤波器，用于电力系统离散数据基波提取(This program is a Chebyshev low-pass filter for extracting the fundamental power system discrete data)

This project will do encryption by reserving room before encryption for better performance of the compressed image

说明：  利用锁相环来实现MSK信号的定时同步，采用的是gardner算法(Using phase-locked loop to achieve timing synchronization of MSK signal, Gardner algorithm is adopted.)

通过虚拟阵元进行DOA估计，相控阵天线的方向图（切比雪夫加权），基于kaiser窗的双谱线插值FFT谐波分析，实现了对10个数字音的识别，旋转机械二维全息谱计算，通过matlab代码。
