Abstract
An apparatus for a base station of a wireless communication network includes a detector to detect an access code received from a mobile station in each of a plurality of time durations and to detect a timing offset of the access code detected in each of the plurality of time durations, an estimator to estimate a carrier-to-interference noise ratio (CINR) during each of the plurality of time durations, and a determining unit to determine a timing offset correction value to be applied to subsequent signals from the mobile station using the CINR, the timing offset, and the access code detected in each of the plurality of time durations.
