An orthogonal frequency division multiplexed (OFDM) receiver achieves improved frequency synchronization by generating a fine frequency offset of an OFDM packet with a two-channel frequency offset estimation scheme. Concurrent autocorrelations are performed with training symbols delayed by one and two...http://www.google.com/patents/US20040190438?utm_source=gb-gplus-sharePatent US20040190438 - System and method for two channel frequency offset estimation of OFDM signals
