matlab方面的书。对初学者很有帮助。里边介绍的很系统。(matlab' s book. Helpful for beginners. Is introduced inside the system.)

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 carry 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.)

matlab的绘图程序，希望对大家有用。(matlab drawing process, in the hope that useful to everyone.)

说明：  Matlab遗传算法工具箱自己创建的绘图函数（7.1版本工具箱帮助文件中有）(Matlab genetic algorithm toolbox to create their own mapping function (7.1 version of the toolbox to help file))

主要是用于图像能量的提取，效果不错，可以使用(Is mainly used to image the extraction of energy, the effect is good, can use)

create B-spline in 2D and 3D space Matlab

that is useful code for communication

1利用3阶和四阶B 样条函数构造正交小波的方法；用matlab实现构造正交小波的数值实现。 (1 using 3-order and fourth-order B-spline function to construct orthogonal wavelet method achieved by constructing the orthogonal wavelet matlab numerical implementation.)

对于通行工程里的两种调制方式PAM和QAM进行了性能仿真，并对他们的性能进行了比较。有信噪比，误码率等重要参数比较。还有具体的文档说明。(For the passage of two works in the PAM and QAM modulation for the performance simulation, and their performance compared. There is signal to noise ratio, bit error rate and other important parameters. There are specific documentation.)

关于matlab的比较初级的siso设计。(a design for siso of matlab)
