Abstract
In a method for determining timing information in a receiver, a receiver receives a modulated signal and demodulates the modulated signal using an demodulator to produce a demodulated signal. An analog to digital converter converts the demodulated signal to a digital signal and first and second signals are produced from the digital signal. The first signal is analyzed to determine a first phase difference with respect to different portions of the signal, and the 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. A joint estimate of a sampling period offset and a carrier frequency offset is generated based on the first phase difference and the second phase difference.
