Patent ID: 6891898

Claim:
A system for recovering a symbol timing offset and carrier frequency error from an orthogonal frequency division multiplexed (OFDM) signal, said system comprising: means for receiving an OFDM modulated signal representing a series of OFDM symbols, each OFDM symbol including a leading portion and a trailing portion thereof, said means for receiving providing a received signal to an output thereof; peak development means developing a boundary signal having a plurality of signal peaks representing a symbol boundary position for each received OFDM symbol, each said plurality of signal peaks being developed responsive to an amplitude and phase correspondence produced between the leading and trailing portions of each said received OFDM symbol; means for enhancing signal peak detectability of said boundary signal; and means for establishing a temporal position indicative of said symbol boundary position from at least one enhanced signal peak output from the enhancement means, said temporal position representing a received OFDM signal symbol timing offset.
