Abstract: A method of timing synchronization in sub-band based ultra wideband systems, includes obtaining a coarse estimate of an offset in a time domain at a sub-sampled rate, and obtaining a fine estimate of the offset in an analog domain. The method further includes correcting a timing in the analog domain by transforming the fine estimate to an equivalent phase for the correcting.
