... Illustration of the time behavior of PU and SU under two different access policies. 2. System Model and Problem Formulation In this section, we first present the system model and the time behaviors of PU and ... behavior of the PU is not time slotted and switches between ON and OFF states. Furthermore, we model the time behavior of the PU by a two-state ON/OFF CTMC,...
