说明：  用于模拟光纤中的非线性薛定谔方程，包含了色散、非线性等现象的模拟，对与想了解脉冲在光纤中的传输变化非常有帮助(Used to simulate the optical fiber in the nonlinear Schr&ouml dinger equation, including the dispersion, nonlinear phenomena such as analog, pulse on and want to understand changes in the transmission fiber is very helpful)

着重介绍了OFDM 系统 中的峰值平均功率比（PAR）问题，给出了峰值平均功率比的定义以及高PAR 产 生的原因和它带来的问题，并且分析了OFDM 系统内PAR 的分布，最后对国内 外各种降低PAPR 的方法进行了简单介绍。(Focuses on the OFDM system The peak to average power ratio (PAR), and gives the definition of peak to average power ratio and high PAR production Health reasons and problems it brings, and the analysis of the distribution of the PAR of OFDM system, the last of the domestic A variety of methods to reduce PAPR outside a brief introduction.)

电机的MATLAB仿真，包括步进电机，同步电机，直流电机的仿真源代码。内容全面(Motor MATLAB simulation, simulation source code, including stepper motors, synchronous motors, DC motors. Comprehensive)

this is a matlab code for linear predictive coder

运动目标跟踪 matlab, 准确、有效(kalman human tracking.rar)

THis file contains codes for ploting scatter plot and eye diagram

说明：  泊松方程 matlab解偏微分方程定界问题和图像(matlab matlab)

说明：  滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)

求解指派问题，再输入指令后，根据信息自动快速的求出最佳分配方案(Solve the assignment problem, and then enter the command, according to the information automatically and quickly find the optimal allocation scheme)

gnss跟踪算法仿真，使用matlab编译，文件类型为.m(Tracking algorithm simulation)
