Abstract
In one aspect, an apparatus includes: a buffer to store orthogonal frequency division multiplexing (OFDM) samples of one or more OFDM symbols; a fast Fourier transform (FFT) engine coupled to the buffer, the FFT engine to receive the one or more OFDM samples from the buffer and convert each of the one or more OFDM samples into a plurality of frequency domain sub-carriers; and a timing control circuit coupled to the buffer. The timing control circuit may control timing based at least in part on a difference between a first correlation sum for a first portion of a cyclic prefix of a first one of the one or more OFDM symbols and a second correlation sum for a second portion of the cyclic prefix.
