Abstract

A method (500) and a mobile station (160) for determining a code phase are described herein. The mobile station (160) may generate a first auto correlation function (ACF) associated with correlation samples over a range of code phases corresponding to a line-of-sight signal. The mobile station (160) may generate a second ACF within the mobile station based on measured correlation samples over a range of code phases. The mobile station (160) may compare the first ACF to the second ACF to generate a code phase offset between the first and second ACFs. The mobile station (160) may adjust the first ACF to match the second ACF.
