On distribution of SIR in dense D2D deployments

This paper investigates the signal-to-interference (SIR) performance of dense device-to-device (D2D) deployments that are becoming reality in modern urban environments. By utilizing methods from stochastic geometry, we propose two closed-form approximations for the SIR probability density function, as well as verify them against the corresponding systemlevel simulations. We also discuss the most interesting properties of the introduced models, which yield important conclusions on respective system design. © VDE Verlag GMBH, Berlin, Offenbach, Germany.
