Abstract
A method and system is provided for enabling spectrum sensing capability in a network having at least one primary user and a plurality of secondary users configured to communicate using a shared spectrum. The methods and systems include receiving values from sensors corresponding to received signal strength from a primary user in one or more frequencies of the shared spectrum. The values are used to interpolate at least one additional value between the sensors. A detection threshold is determined for sensing a signal transmitted from the primary user based on an acceptable amount of interference. The primary user is then determined to be transmitting in the one or more frequencies of the shared spectrum if any of the values received from the plurality of sensors or the at least one additional value interpolated along the path exceeds the detection threshold.
