Abstract (en)
[origin: WO03024042A1] A carrier offset recovery method and apparatus are provided that use a dual sequence has a period N=2n that is less than a second sequence having a period M=2m. The apparatus includes an error corrector circuit that combines the range from one offset estimation with the precision of the other. To obtain a very large range for the carrier offset one can employ one or more additional stages. For example, one can use a sequence with a period of P=2p samples where P<N. Offset estimation would be performed first on the P-sample sequence, then on the N-sample sequence and finally on the M-sample sequence.
