这是一个非常好的程序，主要用来解决模糊变结构控制问题，是我导师给我的，现在和大家分享。(fsekjl dfsdfj psdfsdf sdfklsdjfopsd)

通过excel将输入读入matlab中，计算文件第四列元素的最大值，最小值和均方根值，对应z波面拟合中的PV RMS的计算。上传文件中包括excel文件(Input read by excel in matlab to calculate the column IV of document elements of the maximum, minimum and RMS values, corresponding to zernike Wavefront fitting of PV RMS calculation)

matlab通带滤波，是在频域内实现的，最好用于地震波，或其他一些信号逐渐衰减的情况(bandpass filter,used for strong motion data process for better. because the software carry out the filter function through fft)

eliminate the steady-state error to a step reference

用matlab实现的运动员号码识别系统，主要是运动员在运动的过程中辨别他的号码。(Using matlab athletes realize number identification system, mainly athletes in the course of the campaign to identify his number.)

Using wavelet transform to calculate the heartbeat rate of ECG

本文在介绍MIMO无线通信系统模型的基础上，通过对比分析几种常用空时编码方法，选定空时分组码对信号进行编码并建立瑞利衰落信道模型，通过对两发一收及两发两收系统的仿真，研究接收天线数对系统接收信号可靠性的影响。之后进一步扩展到不同发射矩阵条件下研究多发一收系统的频谱利用率及误符号率，分析不同天线数目，不同发射矩阵条件下空时正交分组码检测算法的性能。(This paper introduced the MIMO wireless communication system model, through the comparative analysis of several commonly used method of space-time coding, grouping code for the selected space-time signal is encoded and establish Rayleigh fading channel model, through two rounds one and two rounds of closing Simulation of two closed systems, research receiving antennas to receive signals affect the reliability of the system. After further extended to study the conditions under different emission matrix of multiple spectral efficiency and symbol error rate of a closed system, analyze the different number of antennas, the performance under different emission matrix orthogonal space-time block codes condition detection algorithm.)
