Method and apparatus for detection and correction of oscillator frequency error within a wireless communication system receiver. A frequency estimator having block correlators, conjugate product and sum, accumulation block, multipath detection and a loop filter (accumulate block) (adaptive bandwidth). The multipath detection includes a search block, threshold detection block and a block for combining multipath components. The frequency difference attained between a base station (BS) local oscillator (LO) and a user equipment (UE) local oscillator is such that the UE LO does not deviate more than 0. 1 PPM from the BS LO.
