The system for recovering symbol timing offset and carrier frequency error from an orthogonal frequency division multiplexed (OFDM) signal includes a receiver circuit for receiving an OFDM modulated signal representing a series of OFDM symbols, and providing a received signal to an output thereof. A peak development circuit is included for developing a signal having a plurality of signal peaks representing symbol boundary positions for each received OFDM symbol, where each of the signal peaks is developed responsive to an amplitude and phase correspondence produced between the leading and trailing portions of each of the received OFDM symbols.

Why it's free to use
- Filed February 17, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 17, 2020.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
