SYSTEMS AND METHODS FOR ENHANCED ATC OVERLAY MODULATION

摘要

The present invention discloses methods for providing an enhanced data link using overlaid modulation. In particular it is directed to a method to resolve phase within a PSK-encoded carrier, the method comprising determining a desired phase shift to apply to a PSK-encoded carrier; calculating a compensatory phase shift by dividing the desired phase shift by a predetermined number of compensation cycles; and applying the compensatory phase shift to the PSK-encoded carrier for the predetermined number of compensation cycles. The method further discloses that the predetermined number of phase shifts comprises the number of cycles in the PSK-
