基于ARM+DSP的3GPP移动通信系统标准MAC层设计

3GPP Mobile Communication System Standard MAC Layer Design Based on ARM + DSP

摘要:

目前高校通信类专业所用实验设备主要完成调制、交织、信道编码和系统信令实验,较难配合3GPP标准来完成教学和科研及课程设计及毕业设计的任务;在充分研究3GPP标准文档后,在自主开发的ARM和DSP单板上完成了3G系统UE,NODEB,RNC的协议开发及4G系统的终端及网络侧的协议开发;文中对MAC层协议的功能及算法的具体实现进行了研究,包括MAC的发送控制、接收控制、业务量测量等MAC主要功能;实现了符合3GPP标准的移动通信系统教学与研究平台,并跟踪整个系统的运行;较好地配合了教学和科研工作,对3GPP标准的演进过程的跟踪教学与研究也有一定作用。

Abstract:

Experimental equipment is mainly used in communication engineering in colleges and universities, interleaving, channel coding and modulation system signaling experiment, difficult to cooperate with the 3GPP standards to complete the teaching and scientific research and the course design and graduation design task. After fully research 3 GPP standard document on the independent development of ARM and DSP veneer UE, completed the 3 G system NODEB, RNC protocol development and 4 G system terminals and network development side of the agreement. Function and algorithm of MAC layer protocol in this paper the concrete realization are studied, including MAC control sending and receiving control, MAC main functions such as volume measurement. The realization of the mobile communication system of teaching and research platform with 3GPP standard, and follow the whole system operation.Cooperate with the teaching and scientific research work. Tracking the process of the evolution of the 3 GPP standard teaching and research also has certain effect .
