Performance Analysis of full-duplex relaying Networks: an Application in 5G

Abstract

This dissertation deals with the wireless full-duplex relaying networks where the relay node is employed with energy harvesting (EH) capability. First, various communication and harvesting protocols are investigated, including amplify-and-forward (AF) and decode-and-forward (DF) for relaying strategies, and time-switching (TSR) and power-splitting (PSR) for EH. In particular, I provide the derived closed-form expressions describing key performance factors, including outage probability (OP), throughput, Ergodic capacity, and study the impact of configuration parameters such as channel conditions, transmit power, energy harvesting protocol parameters, etc. on the overall system performance. Secondly, this dissertation aims to study the impact of antenna configurations on the outage probability and throughput, which are two key performance factors of EH-based wireless full-duplex relaying networks. Regarding antenna configurations for EH, two configurations for antennas at the relay node are considered, namely, using single-antenna configuration or two-antenna configuration for collecting the energy from source nodes, while only one antenna is used to forward the information signal to the destination. To further enhance the system performance, multiple-input multiple-output (MIMO) communication scheme is also considered in my dissertation, especially, three diverse techniques, i.e., Zero Forcing at Transmitter (TZF), Zero Forcing at Receiver (RZF), and Maximal Ratio Combining (MRC), which are employed to strengthen the performance of MIMO system. Finally, this dissertation deals with the performance analyses of the energy harvesting based full-duplex relay networks for various transmission modes including instantaneous, delay-limited and delay-tolerant transmissions. Specifically, the outage probability and the throughput for the proposed system as the functions of all system parameters such as the position of relay nodes, the data transmission rate, the noise at the source and relay as well as the energy conversion factor are derived. Based on the analyses, optimal energy harvesting parameters and best communication strategy for the presented model are proposed. All analytical results are validated by Monte Carlo simulations.
