A method of estimating the carrier frequency of a signal is disclosed. The method comprising the steps of initializing a time average vector to zero, selecting a user-selectable time segment to divide a received signal into. A signal is received, and divided into the user-selectable time segments. A spectral peak vector is calculated by performing a spectral estimation process on the user-selectable time segment divided signal. A first correlation vector is calculated on the spectral peak vector, and a second correlation vector is calculated from the spectral peak vector and the first correlation vector. The time average vector is appended with the result from the second correlation vector, and the process repeats for each time segment the received signal was broken into. The carrier is estimated using the most commonly occurring frequency in the time average vector.
