Outage probability of the tagged femto user. Outage probability of the tagged femto user (or any randomly chosen femto user) under perfect and imperfect sensing scenarios. The system parameters are set as P F = 22 dBm, P P = 42 dBm, α = 4, p RB = 0.8, p tx = 0.7, μ = 0.2, μ p = 1, K = 1, \( {\lambda}_M^{\hbox{'}}=12 \) , λ F = 800, and \( {\lambda}_F^{\hbox{'}}=700 \).
