Effect of D on outage probability of the tagged macro user. Effect of D (the defined exclusion region around the tagged macro user) on outage probability of the tagged macro user in the presence of both the macro and femto-BSs. 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, λ M = 50, \( {\lambda}_M^{\hbox{'}}=12 \) (in (a)) and \( {\lambda}_M^{\hbox{'}}=25 \) (in (b)).
