K_MEANS_v2.1

现代通信系统(matlab版本)第二版，第一章的第一个例题程序.(Modern communication systems (matlab version) second edition, the first chapter of the first Example program.)

给出了利用matlab程序编写的脉冲星EKF仿真程序，对噪声进行时变分析(pulsars navigation EKF)

pdcontroller for matlab

Control of induction generator

时延与波包周期的关系 Cycle delay and the relationship between the wave packet

模糊转矩控制 本例采用模糊转矩控制效果较好(Torque fuzzy control in this case using fuzzy torque control is better)

一篇学习simulink的仿真资料，包括一定的例程程序(A learning simulink simulation information, including certain routine procedures)

对于卫星系统的优化，目前比较前沿的是基于多学科优化(MDO)的方法，文中重点对此方法进行了介绍。(For the satellite system optimization, more cutting edge is based on the current multi-disciplinary optimization (MDO) methods, the paper focus on this method were introduced.)

说明：  matlab里面使用三倍中误差法消除观测粗差，去除噪声。(matlab error method which uses three times in the elimination of Gross Errors, remove noise.)

QPSK调制解调仿真 从基带信号产生——IQ映射——调制——信道加噪——解调——判决及反映射——接收信号输出，每个步骤都画出了图形。 (QPSK modulation and demodulation simulation generated from the baseband signal- IQ Mapping- Modulation- channel plus noise- demodulation- judgment and reflect radio- reception signal output, each step to draw the graph.)
