短路电流计算MATLAB程序，适合电力系统分析学习(Short-circuit current calculation MATLAB program for power system analysis study)

基于IEC61131—3标准的连续定位运动模块MC—PositionProfile，可以使用户方便的定义几点，然 后实现加速度平滑变化的运动。虽然其保证了加速度的平滑过渡，但没有考虑轴会发生反转，本文讨论的是 在保证加速度变化平滑的基础上实现轴的单向运动。(IEC61131-3 standard based on the continuous positioning movement module MC-PositionProfile, allows the user to easily define points, and then change to achieve smooth acceleration of the movement. Although its acceleration to ensure a smooth transition, but did not consider the axis will be reversed, this discussion is to ensure the smooth acceleration on the basis of changes in one-way movement axis.)

多目标粒子群算法 本人自己编写 经过测试可以(mpso writed by myself canbe used )

说明：  插值与拟合问题的matlab程序，并配有幻灯说明，供大家参考！(Interpolation problem with matlab fitting procedures and is equipped with slide shows that for your reference!)

用于ADC的动态性能评估,有matlab的示例程序(For the ADC' s dynamic performance evaluation, have matlab sample program)

摘要:正交频分复用(OFDM)是第四代移动通信的核心技术。该文首先简要介绍了OFDM基本原理,重点研究了理想同步情 况下,保护时隙(CP)和不同的信道估计方法在高斯信道和多径瑞利衰落信道下对OFDM系统性能的影响。在给出OFDM系 统模型的基础上,用MATLAB语言实现了整个系统的计算机仿真并给出参考设计程序。最后给出在不同的信道条件下,保 护时隙、信道估计方法对OFDM系统误码率影响的比较曲线,得出了较理想的结论。 (O FDM is the key techno logy of 4G in the field of mobile comm unication.In this article O FDM ba sic p rinc ip le is briefly in troduced.Then,the influence of CP and d iffe rent channe l e stim a tion on the system pe rfo rm ance is emp ha tica lly analyzed respectively in Gauss and R ayle igh fading channe ls in the cond ition of ideal synchronization.B e sides,based on the given system mode l O FDM system is compu te r sim u la ted w ith MA TLAB language and the refe rentia l design p rocedure is given.Fina lly,the B ER cu rves of CP and channe l e stim ation a re given and comp ared.The conclusion is sa tisfac to ry. )
