Abstract
A base station for compensating for frequency offsets is described. The base station includes a processor and instructions stored in memory. The base station computes a time domain impulse response estimate and applies frequency offset compensation to the time domain impulse response estimate to obtain a time domain offset-compensated impulse response estimate. A frequency domain offset-compensated impulse response estimate is computed. The frequency domain offset-compensated impulse response estimate is used to compute beamforming weights. The base station transmits data using the beamforming weights.
