Constrained Weighted Least-Squares Algorithms for 3-D AOA-Based Hybrid Localization
IEEE Open Journal of Signal ProcessingSource localization with time-of-arrival (TOA), time-difference-of-arrival (TDOA), time-delay (TD), received-signal-strength (RSS), or angle-of-arrival (AOA) measurements from several spatially distributed sensors is commonly used in practice.

Multi-Array 5G V2V Relative Positioning: Performance Bounds
, 2019 We study the performance bounds of vehicle-to-vehicle (V2V) relative positioning for vehicles with multiple antenna arrays. The Cram\'{e}r-Rao bound for the estimation of the relative position and the orientation of the Tx vehicle is derived, when angle ...
