这本书介绍了matlab在信号处理中的应用和例子，同时还讲解了信号处理中的一些重要原理，可以同时巩固大家的基础知识(This book introduces the matlab signal processing applications and examples, and also explain some of the important principles in the signal processing, you can consolidate all the basics)

离散时间信号基本运算，包括序列相加相减、序列位移、序列翻转、序列周期延拓(Discrete-time signal basic operations, including the sequence of addition and subtraction, shift sequence, sequence inversion sequence cycle extension)

用matlab所学的知识，编写最小二乘法拟合程序，以解决物理实验中的最小二乘法拟合曲线以及相关系数等的问题。(With matlab learned, the preparation method of least squares fitting procedure to solve the problems of the least-squares fitting curve and correlation coefficient physics experiments.)

PDEPLOT 通用偏微分方程工具箱功能。(Toolbox PDEPLOT common feature of partial differential equations.)

由于多径和移动台运动等影响因素，使得移动信道对传输信号在时间、频率和角度上造成了色散，如时间色散、频率色散、角度色散等等，因此多径信道的特性对通信质量有着至关重要的影响，而多径信道的包络统计特性成为我们研究的焦点。根据不同无线环境，接收信号包络一般服从几种典型分布，如瑞利分布、莱斯分布和Nakagami-m分布。(Because multipath and mobile and other sports influence factor, makes mobile channel in transmission in time and frequency signal and Angle caused the dispersion, such as time dispersion, frequency dispersion, Angle dispersion, and so on, thus multipath channel of communication with the characteristics of quality is very important, while the effect of multipath channel (the statistical properties become the focus of our research. According to different wireless environment, receiving signals envelope general subject to several typical distribution, such as Rayleigh distribution, rice distribution and Nakagami-m distribution. )

假设检验演示程序 单侧假设检验 书上的源代码 希望对其他人有用(Sided hypothesis test hypothesis testing demo program source code book useful for hope to others)

The main file in this list of programs is "vblast.m". Type "help vblast" on the command line for details.Study the coding by stepping through the program. These programs require around 5000 packets for reasonable plotting accuracy.This has been implemented for a 2x2 system. The reader can program other variations. The program has been tested on MATLAB version 6.0 and above with signal processing toolbox and communication toolbox options.
