An apparatus includes a radio frequency receiver and a timing adjustment unit that contains at least two channel impulse response estimators. The at least two channel impulse response estimators include an on-time estimator and at least one of an early estimator and a late estimator. The apparatus also includes a calculation unit that is configurable to obtain a channel estimate for each measured channel impulse response and to average obtained channel estimates over a plurality of received signal events to determine a timing adjustment in accordance with residual signal power.
