Abstract
A low complexity primary user detection system is disclosed. Signals are filtered to reduce the number of signals that must be processed. Width and PRI of the signals are used to match a constellation associated with a primary user. If the constellation is matched, communication parameters are adjusted to make way for the primary user.
