Abstract

In the context of Internet-of-Things (IoT), big Data analytic and the interconnected world, the scientific revolution is increasing the demand for an improved spectrum utilization. An efficient use of the existing spectrum is required for high data-rate transmission. There are several potential ways of solving the challenges of spectrum scarcity. In-Band Full Duplex (IBFD) and Non-Orthogonal Multiple Access (NOMA) are two techniques that can improve the spectral efficiency (SE) in a 5G and Beyond (5GB) cellular networks. This paper proposes a spectral efficient IBFD scheme, Reflective In-Band Full-Duplex (R-IBFD) algorithm for relay selection to improve security of the system with minimum interference. The interference is basically reduced by the addition of orthogonality between the transmitted and received signal in the IBFD mode. The proposed R-IBFD is evaluated with IBFD, Device-to-Device (D2D) and Artificial Noise (AN). Secrecy Outage Probability (SOP) and throughput is analysed for R-IBFD. The simulation results present the comparison between the R-IBFD and conventional decode-and-forward IBFD communication with one or more users operated as a relay.
