TL;DR: A closed-form expression is derived for the mean SU capacity under the imperfect CSI scenario where the SU cannot always satisfy the peak received interference power constraint at the PU and has to back off its transmit power.

TL;DR: This article focuses on the application of advanced smart antenna technologies to SWIPT, including multiple-input multiple-output and relaying techniques, which have the potential to significantly improve the energy efficiency and also the spectral efficiency ofSWIPT.

TL;DR: In this article, the authors considered a multi-user decode-and-forward relay channel, where multiple sources transmit simultaneously their signals to multiple destinations with the help of a full-duplex relay station and derived an exact achievable rate expression in closed-form for MRC/MRT processing and an analytical approximation of the achievable rate for ZF processing.

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.

TL;DR: An optimal relay selection procedure that incorporates a hybrid relaying strategy, which dynamically switches between FD and half-duplex relaying according to the instantaneous CSI, is investigated.
