Abstract
In a method for detecting a synchronization field in an orthogonal frequency division multiplexing (OFDM) signal, a plurality of discrete Fourier transform (DFT) values corresponding to the OFDM signal are generated. A plurality of magnitude or power values corresponding to the plurality of DFT values is determined. It is determined whether the plurality of magnitude or power values corresponds to a pattern of magnitude or power values. An indication that the synchronization field is detected in the OFDM signal is generated based on whether it is determined that the plurality of magnitude or power values correspond to the pattern of magnitude or power values.
