Abstract
This paper presents a proposal of a new mobile station (MS) location estimation method based on the maximum likelihood function in cellular systems. This method is applied to signal strength, time of arrival (TOA), or time difference of arrival (TDOA) as measurements for location estimation. We evaluate the performance of this new method through simulations under various conditions in case signal strength is measured, including the comparison of the conventional methods.
