Method and system for frequency offset estimation

摘要

A method and system for estimating a frequency offset between a receiver and a transmitter, including the steps of, or means for: (a) receiving a first signal from said transmitter and demodulating the first signal; (b) performing a frequency shift on said first signal by a predetermined frequency factor to generate a second signal; (c) filtering each of said first and second signals; (d) determining the power of each of the filtered first and second signals; (e) determining an upper corner frequency value of the first signal using the power of the filtered first and second signals; (f) determining a lower corner frequency of the first signal using the determined power of the filtered first and second signals; and (g) determining a frequency offset value based on said upper corner frequency value and said lower corner frequency value.
