摘要:随着三网融合进程的推进,手机 CMMB 业务成为了市场热点。再加上手机定位业务的需求越来越大,亟需研制集通信、
多媒体、LBS功能于一体的手机终端。本文提出一种基于 CMMB 技术定位的方案,设计了能够在实现正常接收移动通信信号及 CMMB
广播信号同时,实现室内外精确定位的融合型终端。本文主要介绍了 CMMB 移动定位终端的硬件系统,包括天线、CDMA2000移动通
信模块、CMMB广播及定位信号接收模块、应用子系统等组成部分。该终端将在网格特征匹配算法的基础上实现室内复杂环境下的
高精度定位。

【Abstract】 As the development of works integration, CMMB based on mobile terminal es a hot point of terminal market.
Meanwhile, because of the growing demand of mobile position service , it is needed to develop the mobile terminal which has the function
munication, multimedia and LBS. In this paper, a design of position scheme based on CMMB has been introduced. The integrated
terminal can not only take out munication signal and CMMB signa, but also achieve precise positioning indoors and outdoors.
The CMMB mobile terminal positioning hardware system consists of Antenna, CDMA2000 munication module, CMMB broad-
casting and positioning signal receiver module, application subsystems and ponents. The terminal can achieve high accuracy
