Abstract: Abstract In the last 20 years, the localization of Mobile Station (MS) in cellular networks has become an exciting topic of the multitude of applications related to location information. The localization of MSs below the US Federal Communications Commission is considered the primary driving force to investigate and supply optimum solutions. A new Mobile Station localization technique is proposed, and its efficiency is evaluated in this paper. The proposed technique, hybrid SADOA/AOA, combines the signal attenuation difference of arrival (SADOA), which generates a circle on which the MS may lie, and the angle of arrival (AOA) techniques, which uses trigonometry laws of sine and cosine to locate the MS. This technique uses Taylor series expansion to solve the hyperbolas and Line of Bearings derived by the two techniques individually. Then it proceeds to use the linear least squares algorithm iteratively to find the location. Simulation results showed that the hybrid SADOA/AOA outperforms the conventional SADOA technique without hardware modification, and it can overcome the shadowing effect of the environment.
