MATLAB关于绘图的设置与调整，这里主要举了一个列子说明，包括xy轴的比例、字号、线宽等(related about setting and adjustment of the graphic in matlab)

用viterbi算法和baum-welch训练找到和更新best path(find best path using Viterbi algorithm and Baum-Welch training)

说明：  这里面所有源码均为《通信原理——基于Matlab的计算机仿真》（郭文彬 桑林.北京邮电大学出版社）上的，自己录入整理，均可以运行，方便查找(Communication Principle Simulation)

《数字信号处理——理论、算法与实现》习题13.3,13.4源代码(" Digital Signal Processing- theory, algorithms and achieve" Problem the 13.3,13.4 source code)

说明：  Chec this options of transform in matlab

扩频通信中的gold序列特性仿真研究。(1) 利用MATLAB编程产生Gold序列族；给出每个序列的一个周期的输出； (2) 根据平衡Gold序列产生方法，产生Gold序列族中的所有平衡序列，每个序列给出一个周期的输出； (3) 计算(1)中Gold序列自相关函数，并画出它们的自相关曲线； (4) 计算(2)中Gold序列互相关函数，并画出其中某一序列与其他序列的互相关曲线； (Sequence Spread Spectrum Communication Simulation of gold. (A) the use of Gold sequences generated MATLAB programming given a cycle of each sequence output (2) The balance of Gold sequence generation method to produce Gold sequences of all balanced sequences, each sequence gives a cycle output (3) computing (1) Gold sequence autocorrelation function, and draw their autocorrelation curve (4) computing (2) Gold sequence cross-correlation function, and draw in which a sequence with other sequences cross-correlation curve )

一段关于循环谱解析式的仿真，最终结果进行绘图(Loop simulation of the spectral analytic formula)

This file is the programs of (chapter 1) of book (Modeling the Wireless Propagation Channel a Simulation Approach with MATLAB) which is related to introduction to wireless propagation. It helps you to simulate wireless channel and wireless statistical models with PDF and CDF.
