To satisfy the service requirements of high accuracy and efficient life detection location for search rescue (SAR) missions after a disaster, we developed passive positioning method to locate mobile phones by capturing random access preamble, which can be applied fourth-generation (4G) even fifth-generation (5G) communication systems. We analyzed characteristics procedure system established way detect combining time-difference-of-arrival (TDOA) estimation determine location. Then, performed...
To satisfy the requirements of high-precision locating and life detecting after disaster, this paper proposes a passive positioning method for mobile phone by capturing preamble sequence which can be applied to 4G even 5G communication system. We analyze characteristics random access procedure system present way detect combining time difference arrival (TDOA) estimation solve location. Then we do experiment simulation acquisition, result proves that is feasible has high detection accuracy in...
With the development of wireless communication, there are usually both communication and positioning requirements. In our previous work, we studied power allocation algorithm for user (P-User) based on Multi-Scale Non-Orthogonal Multiple Access (MS-NOMA) downlink signal where all users (C-Users) have same power. uplink case, scheme C-User P-User needs to be considered jointly as C-Users may different this paper, analyze Quality Service (QoS) ranging accuracy MS-NOMA by deriving their simple...
Abstract With the development of mobile communication network, Internet things and base station, super reliable transmission signal anti-interference ability, technology has been popularized in various industries, a large number products have emerged related applications. However, increase caused huge load to station. The limited access resources station also bring high delay conflict risk equipment. Random is first step equipment network. It can reasonably allocate process random access,...
