SYSTEM AND METHOD FOR FREQUENCY OFFSET ESTIMATION, AND RECEIVER USING SYSTEM FOR FREQUENCY OFFSET ESTIMATION

摘要

SUMMARY OF THE INVENTION The present invention provides a system and method for estimating a frequency offset in which deviation is removed. The frequency offset estimation method estimates a signal to ratio (SNR) of a first signal, determines a multiplicative bias removal term as a function of the signal to noise ratio only, and the first signal generating a raw estimate of frequency offset of , and multiplying the multiplication deviation cancellation term by the raw frequency offset estimate to produce a corrected frequency offset estimate of the first signal.
