Poer spectral density of BPSK, QPSK and 16-QAM

对于非线性系统 如duffing和Lorenz系统，使用龙格库塔法求其系统响应，并画出相图和分岔图( For nonlinear systems such as duffing and Lorenz system, seeking its response system using Runge-Kutta method, and draw the phase diagram and bifurcation diagrams)

一份很好的MATLAB课件，对于入门者很实用。(MATLAB, a very good software, very useful for beginners.)

ALOHA接入协议仿真，对吞吐量和时延进行仿真分析，同时对比了有无捕获效应两种情况下的性能(ALOHA access protocol emulation, simulation throughput and delay analysis, and comparison of the performance of whether the capture effect in both cases)

利用matlab 创建用户界面 标准论文版(Using matlab to create a user interface standard paper version)

结合具体应用，以2倍抽取为例，简要分析了多相滤波的基本原理及具体实现方法，并附带了matlab代码，从实验结果可以看出多相滤波可以实现与传统FIR滤波相同的功能。(Combine concrete application, take 200 extracts as an example, the synopsis analyzes the radical principle that the polyphase filters and concretely carries out a method, and supplementary matlab code, can discover polyphase to filter as a result to carry out to filter same function with traditional FIR from the experiment.)

说明：  该程序中包含有各种响应面方法，如一次响应面和二次响应面(response surface method)

说明：  对于给定的滤波器参数，利用脉冲响应不变性法设计数字低通滤波器，并绘出了设计后的数字滤波器的特性曲线。(This code uses impulse invariant method to design a digital low-pass filter under given filter parameters,then it plots the designed filter s characteristic curve.)

matlab中几种常用的程序，对于熟悉matlab编程有很大帮助(some code in matlab，is useful for the new fish)
