matlab环境下实现电阻抗成像的源程序(matlab environment realize the source electrical impedance tomography)

接收信号为加噪声的QPSK信号，通过球的维纳解，实现系统辨识，达到滤波的目的。(Received signal is the QPSK signal plus noise, the Wiener solution through the ball, to achieve system identification, to achieve the purpose of filtering.)

First use EEMD to decompose the original singal to get IMFS,then use FFT to analyse the each IMF,combine EEMD with FFT to get clearer analytic results.

利用ansys计算的应力结果，求出截面内力，再利用材料力学公式求等效应力（此例是求坝基面的等效应力）(ANSYS calculated using the stress results, obtained cross-section of internal forces, and then use the formula for the mechanical equivalent stress (in this case is to strive for the dam foundation surface equivalent stress))

CRC校验，实现基本的CRC校验功能，当mask不同时，修改也相当方便(CRC checksum, CRC checksum to achieve the basic function, when the mask is not the same time, changes are also very convenient)

MATLAB 程式设计与应用,包含了即基本运算函数(MATLAB programming and applications, including that basic arithmetic functions)

基于自适应的遗传算法求解，比标准遗传算法具有更加良好的解集，收敛性能更好(The solution based on adaptive genetic algorithm has better solution set and better convergence than standard genetic algorithm.)

cognitive radio for multi path wireless channels design environments with diffrent models

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标速度信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)
