Abstract

In a cellular system, Multiple-Input/Multiple-Output (MIMO) technique increases the number of links for not only spatially multiplexing data to transmit/receive but also measuring the distance between a base station (BS) and a mobile station (MS) at the same time. Therefore, if the MIMO technique is applied to a system-based location estimation, it must improve the accuracy of location estimate. This paper evaluates the performances of threshold-based Time of Arrival (TOA) location estimation methods in cellular systems. Computer simulation results on the location estimation error reveal that, if we employ no threshold, the selection method is a proper choice, whereas if we can optimally adjust the threshold according the Carrier-to-Noise power Ratio (CNR), the average method is a proper choice.
