We determine the achievable distortion region when the correlated source samples are transmitted by two energy harvesting (EH) sensor nodes to the destination over orthogonal fading channels. A time slotted system is considered in which the energy and the source samples arrive at the beginning of each time slot (TS), and both the correlation between source samples at the two nodes and fading coefficients...
Optimization of a point-to-point (p2p) multiple-input single-output (MISO) communication system is considered when both the transmitter (TX) and the receiver (RX) have energy harvesting (EH) capabilities. The RX is interested in feeding back the channel state information (CSI) to the TX to help improve the transmission rate. The objective is to maximize the throughput by a deadline, subject to the...
In this work,1 we consider the optimization of feedback in a point-to-point MISO channel with an energy harvesting (EH) receiver (RX). The RX is interested in feeding back the channel state to the transmitter (TX) to help improve the transmission rate, yet must spend the harvested energy wisely to do so. The objective is to maximize the throughput by a deadline, subject to EH constraints at the RX...
This work considers the benefits of allowing spectrum sharing among co-located wireless service providers operating in the same multicell network. Although spectrum sharing was shown to be valuable in some scenarios where the created interference can be eliminated, the benefits have not clearly shown for multicell networks with aggressive reuse. We explore this question and show that spectrum sharing...
In this work1, we consider a setting where K Transmitters (TXs) equipped with multiple antennas aim at transmitting to their K respective Receivers (RXs) also equipped with multiple antennas. Without exchange of the user's data symbols, this represents a conventional Interference Channel (IC), while it is a so-called MIMO Network Channel if the user's data symbols are fully shared between all the...
In this work1, we consider the joint precoding across K distant transmitters (TXs) towards K single-antenna receivers (RXs). In practical networks, cooperation between TXs is limited by the constraints on the backhaul network and the common approach to limit the backhaul overhead is to form small disjoint clusters of cooperating TXs. Yet, this limits the performance due to interference at the cluster...
The performance of Selection cooperation in the presence of a malicious relay is analyzed. The malicious relay introduces a new form of Denial of Service (DoS) attack at the physical layer, inhibiting source-destination communication from reaping the diversity and SNR gains produced through cooperation in the network. In this form of DOS attack, the relay does not alter the source information while...
