Abstract
An orthogonal frequency division multiplexing (OFDM) receiver is synchronized to a received signal during one of the short symbols of the preamble of the OFDM signal, using a timing synchronizing circuit that derives timing information from timing components generated by a constellation processing circuit which generates the timing components from frequency domain components obtained by performing a Fourier transform on the OFDM signal.
