Abstract (en)
[origin: WO0186904A1] A method and apparatus for estimate a frequency offset between a carrier frequency of a transmitter and a local frequency reference of a receiver in a communication system. Successive samples of a frequency synchronization signal transmitted by the transmitter and detected by the receiver are collected, and a phase difference is computed between the successively collected samples. The frequency synchronization signal can be a non-sinusoidal signal, e.g., a pilot symbol and/or data employed as a pilot symbol. Phase differences of successively collected samples are computed until <i>N-1</i> phase differences have been computed. The <i>N-1</i> phase differences are added to produce the estimated frequency offset. Adding may be performed using linear regression or by computing a weighted average.
