基于MATLAB的伪随机序列性能分析伪随机序列在现代工程中有广泛的应用，信号的加密及扩频都离不开伪随机序列，因而对伪随机序列的产生及特性的研究变的越来越深入。而在扩频通信系统中，伪随机序列的抗噪性等优良性能十分显著，故而广泛应用于通信系统当中。本文用MATLAB对m序列等常用的伪随机序列进行建模和设计，计算伪随机序列的相关系数，并以MATLAB为基础对为随即序列进行仿真，为便于观察，我们要用MATLAB拟合出相关的曲线图，把不同伪随机序列的相关性作比较，得出其各自相关性的特点。关键词伪随机序列；m序列；相关性；MATLABAbstractPseudorandomsequencehasawiderangeofapplicationsinmodernworks,spread-spectrumandsignalencryptioncannotbeseparatedfrompseudorandomsequence,sostudyonpseudo-randomsequencegenerationandpropertybecamemoreandmoredeeply.Inspread-spectrumcommunicationsystem,excellentnoiseimmunityperformanceofpseudo-randomsequenceisnotableandthereforewidelyusedincommunicationsystems.Thisarticlemodelanddesignpseudorandomsequence,suchasmsequencescommonly,byMATLAB,calculatingofpseudorandomsequencecorrelationcoefficientandsimulatingbasedonMATLABforsequenceimmediately,forthepurposeofobservation,wehaverelatingtothefittingoutofMatlabgraphandcomparedifferentpseudorandomsequencecorrelation,inordertogetcorrelationoftheirrespectivefeatures.KeywordsPseudorandomsequence;msequence;relationship;MATLAB目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc325748980"摘要PAGEREF_Toc325748980\h1HYPERLINK\l"_Toc325748981"AbstractPAGEREF_Toc325748981\h2HYPERLINK\l"_Toc325748982"第一章绪论PAGEREF_Toc325748982\h1HYPERLINK\l"_Toc325748983"1.1伪随机序列的概述PAGEREF_Toc325748983\h1HYPERLINK\l"_Toc325748984"1.1.1伪随机序列的发展历史PAGEREF_Toc325748984\h1HYPERLINK\l"_Toc325748985"1.1.2伪随机序列的应用领域PAGEREF_Toc325748985\h2HYPERLINK\l"_Toc325748986"1.2论文研究的基本内容PAGEREF_Toc325748986\h3HYPERLINK\l"_Toc325748987"第二章扩频通信简介PAGEREF_Toc325748987\h4HYPERLINK\l"_Toc325748988"2.1扩频通信理论基础PAGEREF_Toc325748988\h4HYPERLINK\l"_Toc325748989"2.1.1shannon公式PAGEREF_Toc325748989\h4HYPERLINK\l"_Toc325748990"2.1.2扩频通信系统的模型PAGEREF_Toc325748990\h5HYPERLINK\l"_Toc325748991"2.2直接序列扩频PAGEREF_Toc325748991\h6HYPERLINK\l"_Toc325748992"2.2.1直扩系统简介PAGEREF_Toc325748992\h6HYPERLINK\l"_Toc325748993"2.2.2直扩系统抗干扰
