用pocklington方程矩量法计算半波对称阵子天线的电流分布(Pocklington equation method of moments to calculate the half-wave symmetric time around the antenna current distribution)

本代码使用matlab工具实现了一幅图片的位面图提取，且实现了在某个位面上加密信息、恢复信息的功能。并给出三幅图片的运行结果展示。(This code uses the matlab tool to achieve a picture of the bit plane map extraction, and the realization of the encrypted information in a bit plane, the function recovery information. And gives the results of running three pictures show.)

利用burge算法估计功率谱，并画出不同参数情况下的功率谱曲线。。希望对大家有帮助。(burge algorithm)

fft 16 point matlab code

异步电机的矢量控制，详细的介绍了异步电机矢量控制系统建立的过程，以及仿真结果(Induction motor vector control, a detailed description of the induction motor vector control system established process and simulation results)

产生一个有带内相位噪声，毛刺噪声，白噪声的LO信号。(creative a LO signal with in band phase noise， spurs and noise floor.)

function Px=overlay(N,omega,A,sigma,num) OVERLAY Forms multiple power spectral density estimates. ------- USAGE Px=overlay(N,omega,A,sigma,num) Calculates the periodogram using an ensemble of realizations of a process consisting of a sum of complex exponential in white noise. N : length of the signal omega : vector containing the sinusoid frequencies A : vector containing the sinusoid frequencies sigma : the variance of the white noise num : size of the ensemble (number of periodograms)
