Patent ID: 8296344

Claim:
A method for calculating a time delay and a frequency offset between at least a first and a second signal, the method comprising: providing a first signal and a second signal using a signal generator hardware device, the first signal and the second signal having a common component, the second signal delayed in time relative to the first signal; generating, by a first auto-product function generator hardware device, a first auto-product function using the common component and the first signal; generating, by a second auto-product function generator hardware device, a second auto-product function using the common component and the second signal; generating, by a delay optimization function generator hardware device, a delay optimization function using the first auto-product function and the second auto-product function; calculating, by a time delay calculator hardware device, a time delay using an identified global maximum value of a magnitude of the delay optimization function; and calculating, by a frequency offset calculator hardware device, a frequency offset using the time delay.
