说明：  matlab与信号系统电子书和相关书中代码(matlab and signal systems and related electronic code book)

用matlab实现二次曲面图绘制，用来绘制曲线图(Draw a graph quadric)

该代码主要用于求最短路问题，开发环境为Matlab(The code is mainly used for the shortest path problem, the development environment for Matlab)

matlab动画教程，有关于图形化窗口的创建以及制作(matlab animation tutorials, graphical window on the creation and production)

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与 理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据。 (The introduction was done with the principle of the QPSK modulation and demodulation in digital communications，a script was written by using Matlab program to CalTy out a simulation of the QPSK communication system．which contains the concrete realization of transmit and receive process．The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise，spectral analysis of each module is also done，the results obtained with theoretical results in the main，which provides an effective frame of reference for understanding the performance of QPSK systems，and the practical application in the system to make further designed．)

主成分分析方法在各个变量之间相关关系研究的基础上，用较少的新变量代替原来较多的变量，而且使这些较少的新变量尽可能多地保留原来较多的变量所反映的信息一种方法。(Principal Component Analysis in the relationship between the various variables on the basis of the study, with fewer new variables replace the original more variable, but made them less a new variable as much as possible to retain the original variables that reflect more information methods)

说明：  基于RSSI的论文,讲解其发展现状和应用场合。主要为说明形式(Paper based on RSSI)
