【摘要】 本文主要是对IEEE 802.16e协议的MAC层进行了整体的研究,特别是对自动请求重传(ARQ,Automatic Repeat reQuest)、快速反馈(FFB,Fast FeedBack)和多播广播服务(MBS,Multicast and Broadcast Service)部分进行了专题的深入剖析;并基于该协议进行了相应的软件实现和单板调试。文章中首先介绍了当前移动通信的常用技术和发展现状;其次系统的介绍了IEEE 802.16e协议MAC层的整体框架并着重介绍了其中的ARQ、FFB和MBS部分;接着对基于IEEE 802.16e协议的微波接入全球互操作性(WIMAX,Worldwide Interoperability for Microwave Access)系统的软件框架和启动流程作以介绍,具体分析了其中的数据库子系统(DBS,DataBase Subsystem)和信道控制子系统(CCS, Channel Control Subsystem)子系统;最后通过CHM单板(信道控制板)调试对软件进行测试。本文的主要成果如下:在第二章中对IEEE 802.16e协议的MAC层进行了整体的分析研究,给出了MAC层的清晰框架。特别对其中的自动请求重传、快速反馈和多播广播服务做了更加细致和深入的研究。第三章中,在对IEEE 802.16e协议的MAC层进行了全面分析的基础上,对基于该协议的微波接入全球互操作性系统的软件部分做了分析与实现的工作。首先是对软件的整体框架做了简要的介绍,然后重点分析了其中的数据库子系统和信道控制子系统的软件实现。并在第四章中通过CHM单板的调试来对软件进行了最终的测试。更多还原

【Abstract】 In this thesis, we conduct an overall research on the MAC layer of IEEE 802.16e protocol, especially focus on ARQ (Automatic Repeat reQuest), FFB (Fast FeedBack) and MBS (Multicast and Broadcast Service). And software based on the protocol is realized and tested in CHM board. The thesis begins with the introduction to recent mobile communication technologies as well as their developments, followed by a systematic study on the MAC layer of IEEE 802.16e protocol and a detailed research on ARQ, FFB and MBS. Next, a software architecture of WIMAX (Worldwide Interoperability for Microwave Access) based on IEEE 802.16e protocol is given and then the startup flow of the software is introduced. In the software architecture, we focus on DBS (DataBase Subsystem) and CCS (Channel Control Subsystem). At last, the software is tested in CHM board.The main results of this thesis are as follows: A whole research on the MAC layer of IEEE 802.16e protocol is done and a clear architecture of MAC layer is given. In MAC layer, ARQ, FFB and MBS are detailed researched.Based on a systematical study of IEEE 802.16e protocol, the software of WIMAX based on the protocol is analyzed and realized. Firstly, the overall architecture is made. Secondly, we mainly introduced the DBS and CCS and their software materialization. Lastly, the software is tested in CHM board.更多还原
