Abstract:

In this paper, we analyze the performance of decode-and-forward (DF) dual-hop relaying networks with wireless energy harvesting at the relay node over the generalized η-μ and κ-μ fading channels. In the analysis, the source and destination nodes are equipped with multiple antennas, whereas the relay node is equipped with a single antenna. Exact analytical expression for the system outage probability (OP) is derived and evaluated. The derived OP expression considers two practical energy harvesting techniques, namely, time switching-based relaying (TSR) and power splitting-based relaying (PSR). Some numerical examples are provided to study the overall system performance under different system parameters, such as fading parameters, energy harvesting time, power splitting factor, and signal-to-noise ratio (SNR). Our numerical results are supported with Monte-Carlo simulations to validate the accuracy of our analysis.

I. Introduction

Energy harvesting (EH) is considered as a powerful solution once integrated into wireless communication in order to overcome the networks limited lifetime. Specifically, EH technology collects energy from natural resources (such as solar, wind, and vibration, among others) and synthesized resources (such as microwave power transfer) and transforms it into electricity to power wireless equipments (see [1] and references therein). In recent years, simultaneous wireless information and power transfer (SWIPT) has gained a great deal of attention from researchers wherein both energy and information are transported to the destination via utilizing the same emitted electromagnetic wave [2]. Two practical receiver designs for SWIPT, time switching (TS) scheme and power splitting (PS) scheme, were proposed in [3] and [4] to implement the simultaneous reception of information and energy. Good amount of literature is available openly that have analyzed the performance of SWIPT systems. A simple instance can be considered in [5] wherein the authors have analyzed the outage probability (OP) of a cooperative system with an EH relay. Moreover, it is good to recall that cooperative relaying systems are usually utilized to increase the coverage under dense frequency reuse.
