MATLAB仿真，对产生的包进行分类处理。源程序(MATLAB simulation, and on the classification packets)

统计分析频谱特性，对初步学习matlab的兄弟们有一定的价值(statistical analysis)

Overlap–save is the traditional name for an efficient way to uate the discrete convolution between a very long signal x[n] and a finite impulse response (FIR) filter h[n].

matlab 代码，利用分步傅里叶方法求解NLSE方程(matlab code, solve the equation NLSE)

说明：  对信号进行频域特征提取，先通过傅里叶变换得到信号频谱，再计算频谱特征，包括重心频率，均方频率和频率方差(Firstly, the frequency spectrum of the signal is obtained by Fourier transform, and then the spectrum characteristics, including center of gravity frequency, mean square frequency and frequency variance, are calculated.)

Analyze multiple user interference based Standard Gaussian Approximation (SGA) model and packets collision (PC) model in IRUWB wireless communication system.

The demand of high data rate services has been increasing very rapidly and there is no slowdown in sight. We know that the data transmission includes both wired and wireless medium. Often, these services require very reliable data transmission over very harsh environment. Most of these transmission systems experience much degradation such as large attenuation, noise, multipath, interference, time variance, nonlinearities and must meet the finite constraints like power limitation and cost factor. One physical layer technique that has gained a lot of popularities due to its robustness in dealing with these impairments is multi-carrier modulation technique. In multi-carrier modulation, the most commonly used technique is Orthogonal Frequency Division Multiplexing (OFDM)

常用的DEA交叉模型，是目前广泛使用的效率评价模型之一(DEA crossover model, which is commonly used in DEA crossover model, is one of the most widely used efficiency evaluation models at present.)
