Spectrum sharing: The SU must coordinate with other SUs to share the available spectrum resources and avoid interference. Thus, medium access control (MAC) protocols and functions must work in tandem with the spectrum sensing process [11,12]. This function may include economic models for spectrum sharing and trading. 4. Spectrum mobility: Unlike traditional wireless communication systems, handoff does not only arise due to the mobility of the SU but also due to the behavior of the PU. Thus, the SU must seamlessly switch between available channels whenever a PU reclaims a channel that is being used by the SU.

1 Cyclostationarity-Based Sensing This type of detection uses the cyclostationary features caused by the periodicity in the signal or in its statistics . 4 illustrates a first-order cylcostationarity detector that tries to exploit the periodicity of the mean of the received signal. Higher-order cyclostationarity has also been investigated in the literature. 5. 4 First-order cyclostationarity detector. 5 Second-order cyclostationarity detector. 7b) In practice, few cyclic frequencies are sufficient for a good performance, and the more cyclic frequencies are used, the further the improvements .
