Joint TOA/AOA Location Algorithms with Two BSs in Circular Scattering Environments
Authors: , ,
Abstract: In circular scattering environments, a scenario with two base stations (BSs) that the home BS measures time of arrival (TOA) and angle of arrival (AOA) while the neighboring BS only measures TOA is investigated. By incorporating the coordinates of scatterers as unknowns in the location algorithm, joint TOA/AOA Constrained Algorithm (TA-CA) is proposed. However, AOA equality constraint is not considered. By combining the AOA equality constraint into TA-CA algorithm, a new TA-CA algorithm is proposed. Due to the high computational complexity and nonconvex about TA-CA algorithm, a grid search algorithm is proposed. The grid search algorithm is formulated by introducing two scale factors and utilizing the hybrid line of position algorithm. The performance of the proposed algorithms are assessed and compared with that of existing algorithms through extensive simulation.
