Abstract
Being applicable for almost every scenario, a mobile localization of the cellular network has gained increasing interest in recent years. Since Received Signal Strength (RSS) information is available in all mobile phones, RSS-based techniques have become the preferred method for a localization of Global System for Mobile (GSM) communications. We use a COST 231-Hata propagation model with directional and omnidirectional antennas to determine a position of the target. To compare the performance of accurate mobile location, we consider both a classical hyperbolic technique, based on time difference of arrival (TDOA) using metric RSS measurements extracted from at least four base stations, and a hyperbolic compensation technique (HCT). The simulation results show that the HCT has a better and stable positioning performance on cellular networks. In addition, the frequency dependence of a surface localization is also studied.
