This paper presents a novel localization scheme that leverages on the joint estima- tion of the Angle of Arrival (AOA) and the Time of Arrival (TOA) at the mobile and reference devices. A two-step least squares (LS) location estimator that utilizes the TOA and AOA infor- mation at both the reference and mobile devices is developed. Numerical simulation results in a typical environment demonstrate that the proposed joint localization scheme which uses only one Line of Sight (LOS) reference device, provide much better location accuracy compared to the conventional unidirectional TOA and TOA/AOA localization schemes, which use disjoint metric estimation and three reference devices.
