Abstract:
In a method for determining timing information in a receiver, a first signal is analyzed to determine a first phase difference with respect to different portions of the first signal, and a second signal is analyzed to determine a second phase difference with respect to different portions of the second signal. The second signal is a frequency domain representation of at least a portion of the first signal. An indication of a carrier frequency offset and a sampling period offset are generated based on the first phase difference and the second phase difference.
