Abstract
Outage performance of a device-to-device (D2D) communication system in the presence of co-channel interference (CCI) is analyzed in this paper. Channels for the D2D and CCI signals are assumed to be κ-μ shadowed faded. Maximal ratio combining (MRC) and selection combining (SC) techniques are considered to combat fading conditions. Characteristic function (CF) expression of the D2D system in the presence of CCI is presented. Outage probability and success probability expressions are presented for the MRC and SC schemes. These outage probability and success probability expressions are functions of various CCI, path-loss and channel fading parameters. With the help of numerical results, effects of CCI on the performance of D2D communication system under different channel fading and path-loss conditions are discussed.
Highlights
The continuous development of technology and ever increasing number of connected devices has boosted the requirement of high data rates for efficient communication
Many D2D communication devices coexisting with other wireless devices are competing for limited bandwidth recourses, which may lead to the co-channel interference (CCI) problem
The interferers are assumed to be present at different distances from the receiver of the considered D2D pair
Summary
The continuous development of technology and ever increasing number of connected devices has boosted the requirement of high data rates for efficient communication. D2D communication system can improve data rate and bandwidth efficiency. Many D2D communication devices coexisting with other wireless devices are competing for limited bandwidth recourses, which may lead to the co-channel interference (CCI) problem. The aim of this paper is to analyze the outage and success probabilities of a D2D communication system in an interference limited scenario. Authors in [7], studied outage performance of D2D communication system over a Rayleigh fading channel in the presence of interference. Success probability performance of D2D communication system over Rician fading channel is studied and analyzed in [8]. In [9], authors analyzed the success probability performance of D2D communication system over a Rayleigh fading channel
