Abstract
Channel use in a wireless communication system is monitored for each radio frequency channel spanning a broad allocated bandwidth simultaneously. A transmission having signals in channels spanning the bandwidth is broadband downconverted in analog before being transformed to produce an instantaneous representation of signal levels in each channel. The instantaneous representation is stored. In addition, a statistic characterizing historical use of at least one of the channels in the bandwidth is calculated from the instantaneous representation.
