用 Matlab 编程模拟 李萨如曲线 两互相垂直的，频率成一定整数比例关系的简谐振动合成，合振动为有一定规则的稳定的闭合曲线，称李萨如曲线。运行程序，令a=pi/3,k=3可得李萨如曲线(simulation using Matlab programming Lissajous curve as two mutually perpendicular. frequency of a certain proportion of the whole synthesis of harmonic vibration, a vibration of a certain rules of the stability of the closed curve Li said if Savimbi curve. Operational procedures, a = pi/3, k = 3 available as Lissajous curve)

首先生成如下形式的图片：图中的白条为7象素宽，210象素高，白条间的宽度为17象素。 然后应用多种滤波器进行处理：算术均值，几何均值，谐波均值，逆谐波均值，中值滤波，中点滤波，最大值、最小值滤波等。最后详细比较上述的结果，并分析原因。（内含实验报告）(Pictures first generate the following form: in IOUs 7 pixels wide by 210 pixels high, IOUs between the width of 17 pixels. Then apply a variety of filters for processing: arithmetic mean, geometric mean, harmonic mean inverse harmonic mean, median filtering, the midpoint filtering, maximum, minimum filter. Finally, a detailed comparison of the above results, and analyze the reasons. (Contains experimental report))

本文主要利用matlab编程工具对直接序列扩频通信的捕获过程进行仿真。仿真主要基于滑动相关法的有关理论,先讨论扩频仿真中起着重要作用的m序列的生成问题,尔后讨论调制信号的产生,然后在信号的捕获中分步讨论,先对捕获的流程进行简单的仿真,再依次加入噪声和多普勒频移后进行捕获仿真(In this paper, using matlab programming tools for direct sequence spread spectrum communication capture process simulation. Simulation of the sliding correlation method is based on the theory, first discuss the simulation plays an important role in spreading the m sequence generation problem, the modulation signal generation and later discussed, and the signal captured by stepping discussion processes the captured first simple simulation, and then followed by adding noise and Doppler frequency shift after the capture simulation)
