Spectrum Availability Recheck Scheme (SARS) for Cognitive Radio Systems with Mobility
Woongsup Lee, Dong‐Ho Cho · 2012
We consider the change of spectrum availability which is caused by the mobility of a cognitive radio (CR) user. Given that the CR user should not interfere with a primary user (PU), it should periodically check the availability of the CR band which is being used. Herein, we refer the scheme to check
