Abstract

See full text

Logic may calculate predicted phase rotations based upon more than one previously determined phase rotation. Logic may access memory to store and retrieve previously determined phase rotations to calculate predicted phase rotations. Logic may determine channel information updates such as channel state information and phase correction information from pilot tones that do not travel close to the direct current (DC) tone or the band edge (or guard) tones and replace the missing phase rotations with predicted phase rotations. Logic may skip phase tracking from pilot tones that have traveled close to the DC tone or the edge tones or that experience channel fading, which may result in a predicted phase rotation being more accurate than a phase rotation determined by processing the corresponding pilot tone.
