Single reference mobile localisation in multipath environment

A wireless localisation scheme which requires just one reference device to estimate the mobile location is presented. The proposed scheme utilises the joint time-of-arrival and angle-of-arrival estimation of the line-of-sight path measured at both mobile and reference devices to construct areas of possible mobile devices (APMDs). The intersection of these APMDs will give an estimation of an MD location. Simulations 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.
