METHOD AND APPARATUS FOR CLOCK CORRECTION IN MIMO OFDM

摘要

A method of phase correction at a wireless device includes: estimating a phase slope for an OFDM symbol in a data portion of a packet based on an elapsed time from the start of the packet; measuring a residual phase slope from tracking pilots for the OFDM symbol in the data portion of the packet; and adjusting a phase correction based upon the phase slope and the residual phase slope. Apparatus in a wireless device performs the method and machine-readable media carry instructions for carrying out the method.
