说明：  基于平面波展开 传输矩阵计算2维矩形光子晶体模型 计算可得出相关图谱 handbook中除了参数说明还有参考文献等(Plane wave expansion based on the transfer matrix calculation of 2-D model calculation of rectangular photonic crystal patterns can be drawn from the relevant handbook of parameters except that there are references such as)

泰克经典资料，详细阐述了探头的选择、使用、维护等。(Tektronix classical data, detailed probe selection, use and maintenance.)

说明：  在用matlab的时频分析中，不是所有信号的wvd都是可以，一些特殊的信号要用特殊的窗口来得到较好的效果(using Matlab in the time-frequency analysis, not all signals can be wvd, some special signal use special window to get good results)

基于小波变换的碰磨故障信号的特征提取，可以画出信号原图，轴心轨迹，频谱图以及多层小波变换的重构信号(Based on wavelet transform rubbing fault signal feature extraction, the signal can be drawn artwork, orbit, spectrum and signal reconstruction wavelet multi-)

说明：  基带信号通过高斯信道和瑞利信道的误码率的计算和仿真，并分别与各自的理论误码率曲线相比较(Baseband signal through AWGN channel and Rayleigh channel bit error rate calculation and simulation, and separately with their respective theoretical BER curves compared)

实现BPSK，QPSK，16QAM，64QAM等的调制解调(Achieve BPSK, QPSK, 16QAM, 64QAM modulation and demodulation, etc.)

基于matlab的滤波反投影重建算法，实现了标准2维图像的重建(based on Matlab filtered back projection reconstruction algorithm, and the standard two-dimensional image reconstruction)

先对陀螺仪测量数据进行预处理，每隔100行抽取一行数据，以第7列数据为例，用ALLAN方差法分析出五项主要参数(First gyroscope measurement data preprocessing, extract a row of data every 100 rows, seven of data, for example, ALLAN variance analysis of the five main parameters)
