Abstract
Recently, ambient backscatter-based communication is considered as an appealing approach, which enables energy-constrained nodes to transmit by backscattering ambient signals, and it has the potential of being integrated with RF-powered NOMA network. In this paper, we analyze the outage performance of a two-node system that works on ambient backscattered signal. One energy harvesting relay, working in time switching relaying (TSR) mode, which assists the transmission of NOMA signal of two users, acts as a backscatter device (BD) to transmit its information to a closely located IoT node by backscattering the signal received from two users. The IoT node transmits its information to the relay by backscattering the signal while the relay transmits downlink NOMA to two destination users. We evaluate the outage performance of backscattered signal at the relay and IoT node. System outage of the NOMA users and throughput of the backscattered transmission are also derived. The effect of backscattering factor on individual and system outage of NOMA users, outage of BD users, and backscattered throughput is indicated. Further, we show the impact of time switching factor on outage and throughput of backscattered network. Ergodic capacity of backscattered network is also evaluated.
期刊介绍：
The International Journal of Communication Systems provides a forum for R&D, open to researchers from all types of institutions and organisations worldwide, aimed at the increasingly important area of communication technology. The Journal''s emphasis is particularly on the issues impacting behaviour at the system, service and management levels. Published twelve times a year, it provides coverage of advances that have a significant potential to impact the immense technical and commercial opportunities in the communications sector. The International Journal of Communication Systems strives to select a balance of contributions that promotes technical innovation allied to practical relevance across the range of system types and issues.
The Journal addresses both public communication systems (Telecommunication, mobile, Internet, and Cable TV) and private systems (Intranets, enterprise networks, LANs, MANs, WANs). The following key areas and issues are regularly covered:
-Transmission/Switching/Distribution technologies (ATM, SDH, TCP/IP, routers, DSL, cable modems, VoD, VoIP, WDM, etc.)
-System control, network/service management
-Network and Internet protocols and standards
-Client-server, distributed and Web-based communication systems
-Broadband and multimedia systems and applications, with a focus on increased service variety and interactivity
-Trials of advanced systems and services; their implementation and evaluation
-Novel concepts and improvements in technique; their theoretical basis and performance analysis using measurement/testing, modelling and simulation
-Performance evaluation issues and methods.
