In contrast, the proposed schemes can guarantee the maximum outage probability constraint and the maximum over-interference probability constraint perfectly no matter what value I th,l is set.
Since the maximum outage probability constraint (mathcal {C}_{1}') and the maximum over-interference probability constraint (mathcal {C}_{2}') provide a lower bound and an upper bound for the power consumption Tr B X) respectively, problem (mathcal {Q}^{text {DRM}}_{1}) is not always feasible.
However, it is easy to prove that the maximum outage probability constraint (mathcal {C}_{1}) in problem should be satisfied tightly, indicating an achieved outage probability equal to ρ c.
After some mathematical manipulation, the maximum permissible transmit power P s of secondary source under the outage constraint ϵ of primary receivers is given by P S = X P P P ω θ P S ω β S (16).
More recently, using the stochastic geometry framework, the transmission capacity has been proposed as the maximum density of active transmitting nodes per unit area to satisfy an outage constraint at a given data rate when interferers are randomly scattered and uncoordinated [9].
Its worst-case planning foresaw a maximum outage of just 100,000 customers, or 8 percent of its base of 1.2 million.
Then, when P P > 14 dB, the outage probability of PUs satisfies the outage constraint ϵ.
The primary systems should be allowed a certain percentage of outage so long as the outage probability of primary systems maintains below a predetermined outage constraint.
However, when considering the primary outage constraint, it is more meaningful to improve the SU's performance based on the joint primary outage constraint for S1 and S2.
Madan [6] analyze the energy efficiency issue subject to the overall outage constraint in physical layer.
