说明：  是关于空时编码的，给出了Matlab程序实现，希望有借鉴意义。(on space-time coding, given the Matlab program, he said.)

对数字电路，通信原理，DSP等一些现象的仿真：比如整流器，滤波器，仿真二/四译码器，四选一数字选择器，信号发生器，2FSK信号的调制、滤波、频谱分析等，对DSP中各种滤波的仿真以及通原中的调制解调的仿真等(Digital circuits, communication theory, DSP and some other phenomena simulation: for example, rectifiers, filters, simulation II/IV decoder, four elected a digital selector, signal generator, 2FSK signal modulation, filtering, spectral analysis, DSP filtering on the various links of the original simulation and the simulation of the modulation and demodulation, etc.)

说明：  图论算法 求SAP矩阵的基本思想是图的最短路的问题。 由于铁路的运输费用与线路的长度不是线性关系，必须对铁路网做一些预处理才能套用图的标准最短算法。 (SAP matrix graph theory algorithm for getting the basic idea is to map the shortest path problem. Since the railway transport costs and the length of line is not a linear relationship, we must do some preprocessing on the rail network to apply a standard graph algorithm shortest.)

用matlab对chirp信号进行了仿真，表现出了chirp信号的frft变换积聚效果(Chirp signal using matlab simulation, the performance of the chirp signal frft transform accumulation effect)

You can now convert the sentences in image to a text format

关于时钟同步timing synchronization 的例程，参数可重设，有注释(timing_syn.m timing synchronization )

一种经典的matlab齿轮损伤数据bp损伤识别，有齿轮故障数据(A classic matlab gear damage data bp damage identification, with gear failure data.)

matlab文档(matlab documentation)

电力系统脉宽调制波形，经调试改进，绝对正确(power_pwm)

说明：  数学建模，正态性检验MATLAB程序，经检验，很好，很牛逼！(Mathematical modeling, MATLAB test normal procedures, by inspection, very good, very牛逼!)
