Abstract
A system for synchronization of an orthogonal frequency division multiplexing signal having a first frequency. The system includes filters configured to receive the OFDM signal, and output second signals corresponding to different frequency bands of the OFDM signal. Each of the second signals includes a corresponding synchronization symbol associated with the OFDM signal, and the synchronization symbols of each of the second signals are the same. The system further includes a Fourier transform circuit configured to receive the second signals from the filters, and output the second signals. Each of the second signals has a second frequency. The system is configured to detect the synchronization symbols in the second signals, and detect a start of OFDM symbols in the OFDM signal based on the detected synchronization symbols. The start of the OFDM symbols corresponds to an average of a plurality of estimations of the start of the OFDM symbols.
