【摘要】 非合作定位是不需要移动运营商参与服务的定位类型,针对非合作定位应用的情况分析了TD-SCDMA的协议,首先简要介绍TD-SCDMA标准,包括它的空中接口结构和物理信道结构;其次,针对非合作定位应用分析TD-SCDMA的随机接入过程和鉴权过程;最后分析了TD-SCDMA协议下应用TOA、AOA、TDOA等定位方法进行非合作定位的优缺点,并提出一种TD-SCDMA标准下的一种TDOA定位方法。更多还原

【Abstract】 Non-cooperative positioning requires no mobile operators to participate in the positioning process. Based on this kind of application, the TD-SCDMA protocol is analyzed in this paper. With a brief description of TD-SCDMA standard, including its air interface structure and physical channel structure, the random access process and the authentication process in non-cooperation location-based applications are analyzed. Finally, a comparison of TOA, AOA and TDOA under the TD-SCDMA standard is discussed, and then a TDOA positioning method under the TD-SCDMA standard is proposed.更多还原
