Performance Analysis of Device-to-DeviceCommunication Using Decode-and-Forward-BasedMultiple Relay in the Presence of Co-ChannelInterference

Abstract

This paper analyzes the impact of co-channel interference on deviceto-device communication using the energy harvesting (EH) and decode-andforward (DF) technique at multiple relay nodes. The paper presents closedform expressions for the cumulative distribution function (CDF) of the signalto-noise ratio plus co-channel noise (SINR), as well as expressions for the outage probability (OP), throughput, and available rate (AR) of the network. Furthermore, an asymptotic expression is derived to assess the probability densityfunction (PDF) of the instantaneous SINR, offering a simple and generalizedapproach to understanding its characteristics in relation to OP, throughput,and AR. The analysis results are verified through Monte-Carlo simulationsand implemented using Matlab.
