Abstract
A method, apparatus, and system for spectrum analysis. The method, apparatus, and system for spectrum analysis include measuring energy incident at a frequency in a frequency spectrum corresponding to a channel, but not all frequencies in the frequency spectrum, and determining whether the energy measured at the frequency exceeds a valid channel threshold.
