Abstract Considering the urgent demand for related applications of BeiDou Navigation Satellite System and TD-LTE, this paper studies non-cooperative positioning technology combining the BeiDou and TD-LTE. It does not need or have a cooperation with network and mobile phones which not only reduced the cost of investment and broaden its application domain. The technology of this paper relies on the high-precision location and time service of BeiDou, efficient transmission bandwidth and Multiple Input Multiple Output (MIMO) of TD-LTE system. A complete scheme of real-time and high-precision non-cooperative positioning for mobile phones is proposed. It aims at the Sounding Reference Signal (SRS) of TD-LTE, utilizes a TDOA/AOA hybrid positioning method based on Fractional Fourier Transform (FRFT) and some related simulations are accomplished to verify its feasibility. Keywords BeiDou positioning FRFT

65.1 Introduction Unlike the well-known satellite positioning technology, the non-cooperative positioning technology based on User Equipment (UE) is a kind of passive positioning technology without the cooperation of users. It accomplishes the estimation

of users’ location by capturing the signal from UE. Considering the properties, the non-cooperative positioning is applied to some special areas. For group users, it makes monitoring management and dispatch available by achieving identity and position information of employees. For relief department, it can effectively strengthen emergency rescue capability via swiftly positioning the mobile phones of trapped people on a large scale. For security sector, it can improve the ability to investigate and monitor crime through snugly positioning and tracking the abnormal phones. In 1996, FCC proposed E911 services which requires that the location of an E911 caller be determined with an accuracy of 100 m in 67 % of the cases without modifying UEs. E911 is a typical application of non-cooperative positioning and urge many corporations and universities to do related research. Ian Paul Larsen briefly introduced their project about UE locator in Ref. [1]. Zhu Dali proposed a kind of induced scheme based on encoder to accomplish the UE non-cooperative positioning in Ref. [2]. XuBo do some research on non-cooperative positioning for CDMA2000 in Ref.
