Chapter 65 Research on the Non-Cooperative Positioning Technologies for Combination of BeiDou and TD-LTE

摘要

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.
