通信系统仿真--具有瑞利分布的随机序列，pn序列及其他仿真程序(Communication System Simulation- Rayleigh distribution with the random sequence, pn sequence and other simulation program)

Decryption algorithm of caeser which generate all possible combinations

永磁同步电机模型参考自适应估算电机转速。值得参考。无错。(Model reference adaptive estimation of permanent magnet synchronous motor. Worth reference. No mistake.)

BTC的基本方法，并且编程实现，显示、观察编码后的图像，分析比较压缩性能。(the basic methods and programming, show that the observed image coding, compression performance analysis and comparison.)

说明：  梯度下降法对数据进行分类，并取了四个数据点，对分类进行证明。对梯度下降法有详细的备注。(The gradient descent method classifies the data and takes four data points to prove the classification. There are detailed remarks on gradient descent method.)

说明：  本程序是暂态稳定分析程序，3机9节点模型，对其在pt时刻7号节点发生三相短路故障，并在ct时刻将故障切除进行仿真，最后绘出2号和1号发电机的功角差与时间的关系曲线。发电机模型采用三阶模型，忽略阻尼，电枢电阻取为零；励磁系统仅有量测和放大环节，忽略反馈和电压调节器；负荷采用恒定阻抗负荷。(This program is a transient stability analysis program, three machine nine node model, which has three-phase short circuit fault on node 7 at Pt time, and cut off the fault at CT time for simulation, and finally draw the relationship curve between power angle difference and time of generator 2 and 1. The generator model adopts the third-order model, neglecting the damping and taking the armature resistance as zero; the excitation system only has the measurement and amplification links, neglecting the feedback and voltage regulator; the load adopts the constant impedance load.)

遗传算法（Genetic Algorithm）是模拟达尔文生物进化论的自然选择和遗传学机理的生物进化过程的计算模型，是一种通过模拟自然进化过程搜索最优解的方法，它最初由美国Michigan大学J.Holland教授于1975年首先提出来的，并出版了颇有影响的专著《Adaptation in Natural and Artificial Systems》，GA这个名称才逐渐为人所知，J.Holland教授所提出的GA通常为简单遗传算法（SGA）。(GA (Genetic Algorithm) is a simulation of Darwinian theory of evolution by natural selection and genetic mechanism of biological evolution of the computing model is a natural evolutionary process by simulating the optimal solution search method, which originally developed by the University of Michigan J.Holland Professor in 1975 first proposed and published an influential monograph " Adaptation in Natural and Artificial Systems" , GA This name was gradually known, J.Holland raised by Professor GA is usually simple genetic algorithm (SGA ).)
