Disclosed are systems and methods for signal detection. In one embodiment, a method is provided for detecting a signal. In this respect, the method comprises the steps of determining a normalized measure of a first power within a first frequency band relative to a second power within a second frequency band of an input signal in a network gateway, wherein the first frequency band is within the second frequency band; and, comparing the normalized measure of the first power with a predefined power threshold to detect a presence of an anticipated signal in the first frequency band.
