Artificial Intellegence: backpropagation

程序对2发2收系统进行SVD算法的仿真。发送信号采用QPSK调制，信道为准静态瑞利平坦衰落信道，引入的噪声为均值为0的高斯白噪声，接收端采用最大似然检测算法，仿真其误比特率特性。(The SVD algorithm simulation program 2 admission system. Send signals using QPSK modulation, channel prevail static Rayleigh flat fading channels, the introduction of noise with mean 0 Gaussian white noise, the receiving end using the maximum likelihood detection algorithm, simulation of the bit error rate characteristics.)

运用matlab软件，进行回归运算，方便快捷(Use matlab software, regression calculation, convenient)

说明：  利用leslie人口模型来解决数学建模中的鱼群数量增减的问题： 具体问题在《数学建模与实验》（科学出版社）的153页第四题。(Leslie population model using mathematical modeling to solve the problem of increase or decrease in the number of fish: specific issues in the &quot Mathematical Modeling and Experiment&quot (Science Press) is the fourth 153 title.)

给定三点坐标（二维），得到圆的圆心及坐标，并在matlab中坐图画出圆，并在图中标注原有圆的位置(Given three coordinates (2 d), get the round circle and coordinates, and sit in the matlab picture out of the circle, and mark the location of the original circle in the picture)

本书从Matlab的基础知识入手，在详细介绍各种命令的同时，向读者介绍Matlab在高等数学，线型代数、符号运算、图形图象处理、数据处理等方面的应用和外部接口程序设计。(This book from the start with a basic knowledge of Matlab, in detail the various commands at the same time, to introduce readers to Matlab in higher mathematics, linear algebra, symbolic computation, graphics, image processing, data processing applications and external interface programming.)
