GUI_4

说明：  该程序介绍Matlab时频分析技术及其应用，利用该程序可以分析周期信息(This program is used to get the frequence. )

QPSK的调制解调系统的实现，程序详细给出了调制解调各个部分的方法。自己在matlab上实现过，都出来了(QPSK modulation and demodulation system implementation, the program details the various parts of the modulation and demodulation method. Their implementation in matlab too, are out)

本程序是实现电力系统的故障计算程序，故障后会对导纳矩阵进行修正，很好的进行了仿真(This program is a power system fault calculation program, fault admittance matrix will be revised, a good simulation)

对影像例如SAR，RS等图像进行校正，具有好的效果(calibrate a series of images such as remote sensing image, and etc. )

对ＬＭＳ算法和ＲＬＳ算法进行了仿真，比较了它们之间的性能(On the LMS algorithm and RLS algorithm simulation, compares the performance between them )

定时恢复在接收机中是必不可少的环节，只有定时恢复环节性能良好才能正确解调出信号。 位同步-gardner算法(Timing recovery is an essential part of the receiver, and the signal is demodulated correctly only when the timing recovery is in good performance.)

说明：  变电站选址程序，对研究选址，能源选址的人拿来研究有用，(The procedure of substation location is useful for people who study location and energy location,)

有PMUSIC 校正前和校正后的比较，MIMO OFDM matlab仿真,相控阵天线的方向图（切比雪夫加权）。( A relatively before correction and after correction PMUSIC, MIMO OFDM matlab simulation, Phased array antenna pattern (Chebyshev weights).)

在Matlab环境下实现的FIR滤波器，以通过编译和运行，可用(In the Matlab environment realize the FIR filter, and run through the compiler can be used)
