CDMA通信系统伪随机序列及其系统应用的研究
|
摘要
本文的研究的是直接序列扩频的码分多址(Code Division Multiple Access，简称为：CDMA)通信系统中的伪随机序列技术，包括它的产生方法和性能分析。文中首先对线性移位寄存器序列和混沌序列做了阐述，并对其主要性能做了计算。然后，文中又讨论了一种产生混沌序列的改进方法和级联序列的思想。基于以上的讨论本文提出了一种产生混沌扩频序列的新方法，并对所产生的混沌序列性能做了计算。文中最后采用蒙特卡洛仿真方法对直扩CDMA系统模型应用不同伪随机序列进行扩频的情况进行了仿真，并计算出了系统的误码率，所用仿真工具为Matlab。此外，本文还进一步讨论了影响混沌序列性能的一些因素，验证了文中提出的新的混沌序列所具有的优点。
This thesis is focoused on the PN sequence of Direct Spread CDMA communication system, including it's generation and properties analyzing. At first, this thesis expounds linear-shift-register sequence and chaotic sequence, and calculates the value of their main properties. Then, an improved method of generating chaotic sequence and the iden of serial sequence are talked. Based on all of these talked above a new method of generating chaotic sequence is presented, and it's properties is calculated. At last, this thesis use MonteCarlo simulation method in the given model of Direct Spread CDMA system to calculate the error rate of system which use the every mentioned PN sequences one by one.The simulation tool is Matlab. Additionally, this thesis also analyzes the factors which can influence the properties of chaotic sequence and points out the merits of the new presented chaotic sequence.
