Abstract
In one aspect, an apparatus includes: a front end circuit to process incoming radio frequency (RF) signals into orthogonal frequency division multiplexing (OFDM) samples of a plurality of OFDM symbols; a transform engine coupled to the front end circuit to convert the plurality of OFDM samples into a plurality of frequency domain sub-carriers; a demodulator coupled to the transform engine to demodulate the plurality of frequency domain sub-carriers; a channel estimation circuit coupled to the transform engine to determine a first channel estimate based on a first set of pilot sub-carriers of the plurality of frequency domain sub-carriers and a second channel estimate based on the first set of pilot sub-carriers; and a control circuit coupled to the channel estimation circuit to control a configuration of the demodulator based at least in part on a selected one of the channel estimates.
