This is source Matlab code for Imperialist Competitive Algorithm. This code include a guide file for user

single phase active harmonic filter

A星算法用于路径规划，并包含一个界面，可以用鼠标确定起点和终点，用MATLAB语言编写，可运行。(A star algorithm is used for path planning, and contains an interface. It can determine the starting point and end point with the mouse. It is written in MATLAB language and can run.)

理想低通滤波器滤波器截止角频率wc，阶数Me(filter function hd=ideal_lp(wc,Me))

DOA谱估计实值MUSIC算法把复数协方差矩阵映射成实数矩阵来处理，特征值分解计算量降低了75 ，实值music算法可以分辨相干信号源(DOA in real MUSIC spectral estimation algorithm to map the complex covariance matrices to deal with real, eigenvalue decomposition calculation reduced by 75 , real music algorithm can distinguish between coherent signal source)

该代码主要是实现自适应功能，用Matlab编写！(The code is mainly the realization of adaptive function, using Matlab to prepare!)

多载波调制(Multicarrier Modulation)采用了多个载波信号。它把数据流分解为若干个子数据流，从而使子数据流具有低得多的传输比特速率，利用这些数据分别去调制若干个载波。所以，在多载波调制信道中，数据传输速率相对较低，码元周期加长，只要时延扩展与码元周期相比小于一定的比值，就不会造成码间干扰。因而多载波调制对于信道的时间弥散性不敏感。多载波调制可以通过多种技术途径来实现，如多音实现(Multitone Realization)、正交多载波调制(OFDM)、MC-CDMA和编码MCM(Coded MCM)。其中，OFDM可以抵抗多径干扰，是当前研究的一个热点。(Multi carrier modulation (Multicarrier Modulation) uses multiple carrier signal. It decomposes a data stream into a plurality of sub data stream, so that the sub data stream transmission bit rate is much lower, respectively to a plurality of carrier modulation using these data. )

matlab程序，可以将信息隐藏在每个字节的LSB中(hide message in lsb of every byte)

基于MATLAB的2FSK信号产生于处理，这个程序比较好，希望对大家有用(Based on MATLAB 2FSK signal processing, this program better, we want to)
