Abstract: 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.

Abstract: The present invention is an method of estimating the frequency of a signal by first receiving a signal, forming a row vector, segmenting the row vector; converting the row vector to a first matrix, multiplying the first matrix by a weight, performing a Fourier transform on the result of the last step. These same steps are repeated on a delayed version of the signal. The next steps are calculating a complex conjugate for each result of the last step, forming a cross-spectrum matrix, selecting a magnitude in the cross-spectrum matrix that is above a threshold; and setting an angular frequency of the signal to either the phase of the selected magnitude, the phase of the mean of the complex numbers in the row in which appears the selected magnitude, or the selected magnitude. The frequency of the signal is then set to the estimated angular frequency divided by the product of 2&pgr; and the signal delay period. Additional rows are processed if need be.
