WCDMA扩频通信系统Gold序列的研究
|
摘要
随着3G牌照的发放,中国正式进入3G时代。3G所采用的关键技术也就成为了各国研究的重点之一,其中扩频码的选择就是不可或缺的关键技术之一。本文研究WCDMA系统在扩频操作中用作扰码的Gold序列,其中包括相关序列的产生方法及特性的分析与探讨,重点是平衡Gold序列的获取方法。
本文首先概括介绍了第三代移动通信系统中三大通信标准对地址码的选择,并作了简单的对比;Gold序列是在m序列的基础上由m序列优选对构成的,所以本文分别对m序列、Gold序列的产生、相关性和平衡性等进行了探讨研究并作了对比;设计了各自相关的MATLAB程序,获得了大量的相关数据和仿真图形,对序列的产生及特性作了分析探讨,从而得出了各方面有益的结论。
对平衡Gold序列,本文首先对其性能的优越性进行分析探讨,获得相关数据图形和有益的结论;然后分别对现有获取平衡Gold序列的方法及相关说法都进行了仿真实现及验证,从而指出了各自存在的问题及局限性。为此,在经过反复实验验证与分析研究的基础上,本文提出了一种新方法来获取平衡Gold序列,解决了现有方法条件不够充分的问题,并在此基础上对原有的最后一种方法进行了同样的改进工作,使其条件进一步完善。以MATLAB为实验平台,本文对所给出的结论都作了相关验证,结果表明了所给出的方法及各相关结论的正确性。
WCDMA系统根据自身需求对序列进行了截短使用,所以最后,本文对平衡Gold序列的截短方法及截短后的特性进行了仿真研究,在获得大量数据及图形的基础上得出了有益的结论。
Along with the issuance of 3G licenses, China’s formally entryed into the 3G era. The key technologies used in 3G are focuses of researching in different coutries, thereinto the choice of spreading code which is one of the essential key technologies. This paper studies the Gold sequence used in WCDMA system’s spread spectrum operating as scrambling code, thereinto containing the analysis and discussion of the way to generate and characteristic of related sequences, with focus on the approach to obtain the balanced Gold sequence.
In this paper, firstly, it shortly introduces the different choice of the address code in the three standards of the third generation mobile communication system, and makes a simple comparison; Gold sequence is generated by the m sequence pairs based on m sequence, so this paper makes a discussion and research on the generation、correlation and balance performance of m sequence and Gold sequence respectively, and also a comparison; Designs all the pertinent MATLAB programs to get large numbers of pertinent date and figures; and after the analysis and discussion of the sequences’s generation and chracteristic using the obtained results, puts forward some kinds of useful conclusions.
About the balanced Gold sequence, this paper firstly analyzes and discusses its superiority of performance and gets a large number of pertinent date、figures and useful conclusions; then makes simulate implementation and verifies each of the existing methods and the related statements to obtain the balanced Gold sequence, to point out their own problems and limitations. Therefore, this paper puts forward a new method to obtain the balanced Gold sequence based on validating、analyzing and researching over and over again, to solve the problem of inadequate condition of the original method. And on this basis, it makes the same further improvement on the last one of the original methods to make its qualification more complete. Using MATLAB as the experimental platform, this paper substantiates all the obtained methods and conclusions, and the result indicates the correctness of the new method、improved method and the pertinent conclusion.
WCDMA system uses the shortened balanced sequence according to their needs, so this paper simulates and researches the methods to short the balanced Gold sequence and the characteristic of the shortened balanced Gold sequence, puts forward some useful conclusions after obtaining a large number of dates and figures.
