A novel wireless localisation scheme which requires just one reference device to estimate the mobile location is presented. The proposed scheme utilizes the joint Time-of-Arrival (TOA) and Angle-of-Arrival (AOA) estimation of Line-of-Sight (LOS) path measured at both mobile and reference device to construct areas of possible mobile device (APMDs). Intersection of these APMDs will give an estimation of MD location. Simulation in light and heavy multipath environments show that the performance of the proposed single reference localisation scheme dramatically improved the location accuracy as compared with the conventional localisation techniques that use four reference devices.
