In this paper, we study the performance of receive spatial modulation (RSM) with simultaneous wireless information and power transfer (SWIPT) capabilities. RSM is a multi-antenna modulation scheme, where the information bits are encoded into complex constellation symbols and the indices of the receive antennas. We show how RSM can be combined with SWIPT, by allowing the receivers to increase their...
This work deals with the problem of distributed resource allocation in MIMO MC MAC networks. The assignment between users and subcarriers is allocated together with the users' transmit powers for energy efficiency maximization, by means of a novel approach which merges the popular Dinkelbach's algorithm with stable matching. A distributed algorithm is presented, which can be implemented in a fully...
The problem of energy-efficient resource allocation in multiple-antenna wiretap channels where transmit antennas are correlated is investigated. The use of artificial noise (AN) in combination with only statistical channel state information (CSI) at the legitimate transmitter is considered. The goal of this work is to do the resource allocation such that the amount of bits which can be reliably and...
The problem of resource allocation for energy-efficient secure communications in multiple input multiple output multiple-antenna eavesdropper (MIMO-ME) systems is investigated. Unlike most papers dealing with physical layer security, in this paper the goal of the resource allocation process is not only to maximize the secrecy capacity, but also the system secrecy energy efficiency (SEE), defined as...
Energy-efficient resource allocation in a single-user, amplify-and-forward (AF), relay-assisted, multiple-input-multiple-output (MIMO) system is considered in this paper. Previous results in this area assume that perfect CSI is available for at least one of the source-relay and relay-destination channels. Instead, the case in which statistical CSI is available for both the source-relay and relay-destination...
The issue of energy-efficient resource allocation in a multi-user, amplify-and-forward, relay-aided MIMO system is considered. The transmit covariance matrices and the relay amplification matrix are optimized in order to maximize the systems global energy efficiency, defined as the ratio between the system achievable sum-rate and the total consumed power. In the definition of the consumed power, both...
