Outage probability as a function of P _S = P _R for the DF relaying at the end-to-end spectral efficiency R = 1 bps/Hz in Rayleigh fading channel with path loss exponent α = 4, noise variance ${\sigma }_R^2={\sigma }_D^2=1$ and interference power P _iR = 0.05 × P _S ( P _iR = P _iD ). (a) Different intensity of interferers λ case when distance of each node d _SR = d _RD = 1.5. (b) Different distance d _SR and d _RD node pair case when intensity of interferers λ = 0.001.
