Abstract

Cognitive radio (CR) technology provides a new approach to solve the problem of wireless spectrum resource scarcity by allowing secondary users (SUs) to access the licensed spectrum in case that SUs do not interfere primary user (PU). One of the most challenging tasks in CR is spectrum sensing. This paper concentrates on the state change of PU's disappearance and analyzes the agility of spectrum sensing via evaluating its sensing time. Some expressions for sensing time are deduced. Based on these expressions, this paper also investigates how to optimize the sensing agility by choosing an appropriate detection period. Simulation results are provided to illustrate the validity of agility analysis and agility optimization in this paper.
