With the increasing penetration of renewable energy resources and plug-in electric vehicles (PEV) in the smart grid, the problem of phase imbalance in a three-phase distribution system becomes more challenging. In this paper, we propose a phase balan

Long-range radio-frequency wireless charging has received more and more attention in recent years. Unlike the literature that focuses on the mobile charging scenario, which is formulated as a path-planning problem, we consider a static network that c

In many survey-free Wi-Fi indoor localization systems, including the Adaptive indoor Wi-Fi Positioning System (AWPS) we proposed earlier, there is a need to associate unlabeled measurements to a floor plan. In this paper, we address the problem of ho

As a candidate power supply solution for the Internet of Things, radio frequency (RF) energy harvesting has attracted great attention recently. In this paper, we consider an RF wireless-powered network, which consists of a dedicated power beacon (PB)

In this paper, we investigate the tradeoffs between storage and latency for a k-user cache-aided relay interference channel with K antennas at the relay when channel state information (CSI) is not available at the transmitters. We propose a cache pla

We consider a two-user multiple access channel (MAC) with a wireless-powered relay-to-destination (RD) link, where the relay harvests energy from a radio frequency (RF) signal sent by a dedicated Power Beacon (PB). Each frame is divided into three ph

We consider a two-user multiple access channel (MAC) with a wireless-powered relay-to-destination (R- D) link, where the relay adopts the decode-and-forward (DF) relaying strategy and operates in half-duplex mode. Each frame is divided into three pha

Interference alignment (IA) has been shown to be a promising technique for achieving the optimal capacity scaling of a multiuser interference channel at asymptotically high-signal-to-noise ratio (SNR). However, in practical communication systems, mit
