说明：  可在MATLAB生成的fig图像中再创建一个图框，用于显示曲线、图形的局部放大。(A frame can be created in the fig image generated by MATLAB, which can be used to display the local magnification of curves and graphs.)

蚁群算法及应用，这本书不错，里面讲得也很详细(Ant colony algorithm and its application, this book is true, which also speaks in great detail)

多维小波matlab工具箱，可以和matlab自带的小波工具箱配合使用。(Multi-dimensional wavelet toolbox matlab, matlab can bring their own use of the wavelet toolbox.)

说明：  伪随机码或称PN码，是扩频通信中不可缺少的一种序列。扩频通信，简单的说来就是通过一组相关性很强的伪随机序列，使原有的信号按照伪随机序列的特性出现。从波形上看，原有信号完全淹没于随机的噪声中，达到隐藏信号和抗干扰的目的。接受方只要有相同的伪随机序列，就可以通过伪随机序列很强的相关性将信号还原出来。而m序列，是扩频系统中最长用的伪随机序列。下面的代码就是基于matlab的生成m序列的代码，通过改变初始多项式的值，就可以生成不同阶数的m序列。(Pseudo-random code or PN code, spread spectrum communication is indispensable to a sequence. Spread spectrum communication, a simple to say that the adoption of a group of highly related to pseudo-random sequence, so that the original signal in accordance with the characteristics of pseudo-random sequence there. From the wave point of view, the original signal completely submerged in the random noise to hide the purpose of signal and interference. As long as the recipient has the same pseudo-random sequence, the pseudo-random sequence can be a strong correlation to restore the signal out. And m sequence spread spectrum system is the longest of the pseudo-random sequence used. The following code is generated based on m sequences of matlab code, by changing the value of the initial polynomial, we can generate a different order of the m sequence.)

OFDM,用于OFDM编程，采用MATLAB，可以学习OFDM调制，用与802。11A，802.16.AC。(OFDM for OFDM programming using MATLAB, we can learn from OFDM modulation, using the 802. 11 A, 802.16.AC.)
