Joint AOA/RSSI based multi-user location system for military mobile base-station

In this paper, we propose a 2-dimensional multi-user location system based on local tactical military communication network for one mobile base-station (BS). The proposed system estimate a location with joint use of angle of arrival (AOA) and received signal strength indication (RSSI) ranging. The locations of multi-user can be estimated with uplink orthogonal frequency division multiple access (OFDMA) signal. Simulations are performed with IEEE 802.16e mobile WiMAX (WiBro) environment. Simulation results demonstrate that the effectiveness of the proposed location system.
