ABSTRACT:
An offset frequency estimation method includes receiving an input signal comprised of complex samples, detecting phases of the complex samples, estimating a temporary offset frequency and an initial phase from the detected phases of the complex samples using a linear regression analysis method, and estimating a final offset frequency by skipping error samples detected using the temporary offset frequency and the initial phase.
