Abstract
A method and device for timing alignment are disclosed. The method includes widening spectra of two signals for timing misalignment estimation; performing cross-correlation between the two spectrum-widened signals; and estimating the timing misalignment between the two signals according to a result of the cross-correlation. Therefore, an accurate time alignment result will be obtained with low complexity. Furthermore, it will be appropriate for all types of signals including separated multi-carrier signals.
