Performance Analysis of Flexible Duplexing using Multi Slope Path loss Models

Abstract

The increasing demand for data traffic can be answered by effective utilization of spectrum through Full Duplexing(FD) Heterogeneous Networks(HetNets).We can achieve better results bys using both Full Duplex and Half Duplex(HD) as Half Duplex gives better results in regions where self interference for FD is higher.We in this paper are presenting distance based duplexing schemes exploiting multi slope path loss models with power control mechanism.Multi slope path loss models captures the effect of environment in better way as compared to single slope path loss models.In our proposed scheme,user will connect to Base Station(BS) based on maximum received power.After connection,the value of critical distance is analyzed after which user can best operate in FD.Open loop power control was implemented for maintaining the fairness of system.Simulated results shows the agreement with assumptions of FD performing better than HD in interference limited models.Results for sum rate & percentage improvement is given for both uplink & downlink.
