Multi Interference Analysis of Two-Way Full-Duplex Decode and Forward Relay System

Abstract

Abstract A number of new technologies have been designed for cooperative communication due to the advancement in wireless communication. High throughput, data rates and high quality of service are required by current generation like 4G and future generation like 5G wireless communication. MIMO antennas have few limitations like hardware complexity, resource requirements when it uses simplex or half duplex mode of operations. To overcome its drawback like self interference, the outage performance analysis of Two way full duplex (FD) decode and forward relay system is carried out by considering residual self interference caused due to the mode called FD when compared to traditional analysis with perfect self interference cancellation. This article investigated the outage performance of a two way network with decode and forward technique in the presence of multi interferers at the source and or destination terminals. Anyway, it was not taken into account in the previous research papers due to the strong self interference (SI) which occurred from the transmitting antenna (Tx) to the local receiving antenna (Rx). The SI has been highly eliminated using various self interference cancellation (SIC) techniques. To improve the outage performance, further optimal power allocation schemes and optimal relay node placement strategies are proposed. Then, simulation results are shown for symmetrical and asymmetrical situations.
