TLDR
It is found that use of double antenna instead of single antenna based transmission at the relay improves the performance significantly and the impact of MRC on the throughput performance is noticeable.Abstract:
The performance of a full-duplex (FD) relaying system is investigated in this paper. The relay is equipped with two antennas (both are trans-receiver). The energy constrained relay is powered by RF energy harvesting. A time-switching architecture is adopted to make communication between a source and a destination. Information received at the destination from both the trans-receiver is combined using a soft combining technique, i.e., Maximal Ratio Combining (MRC). The performance of two protocols, decode-and- forward (DF) relaying and amplify-and-forward (AF), are also studied and compared. It is found that use of double antenna instead of single antenna based transmission at the relay improves the performance significantly. The impact of MRC on the throughput performance is noticeable.read more

MIMO Broadcasting for Simultaneous Wireless Information and Power Transfer
Rui Zhang,Chin Keong Ho +1 more
TL;DR: This paper studies a multiple-input multiple-output (MIMO) wireless broadcast system consisting of three nodes, where one receiver harvests energy and another receiver decodes information separately from the signals sent by a common transmitter, and all the transmitter and receivers may be equipped with multiple antennas.

Ambient RF Energy Harvesting in Urban and Semi-Urban Environments
TL;DR: In this article, a city-wide RF spectral survey was undertaken from outside all of the 270 London Underground stations at street level, and four harvesters (comprising antenna, impedance-matching network, rectifier, maximum power point tracking interface, and storage element) were designed to cover four frequency bands from the largest RF contributors within the ultrahigh frequency (0.3-3 GHz) part of the frequency spectrum.

Wireless Information and Power Transfer With Full Duplex Relaying
TL;DR: This paper proposes two tight SM capacity upper bounds and presents the solution of the optimal time split ratio for the maximum system throughput according to the proposed upper bound and conducts Monte-carlo simulations to reveal the throughput gain of the proposed SM-FD relaying protocol.
