<p>A method and apparatus are provided for recognizing a predetermined sequence within a radio frequency signal received on a Doppler faded radio frequency channel. The method includes the steps of correlating a reference sequence with a sequence of elements of the radio frequency signal received on the Doppler faded radio frequency channel and detecting the predetermined sequence within the received signal when a cumulative power level of subsequences of the correlated sequence exceeds a predetermined power level threshold.
