Interference is traditionally viewed as a performance limiting factor in wireless
communication systems, which is to be minimized or mitigated. Nevertheless, a recent line of …

This monograph presents a unified framework for energy efficiency maximization in wireless
networks via fractional programming theory. The definition of energy efficiency is introduced …

Cell-free systems can effectively eliminate the inter-cell interference by enabling multiple
base stations (BSs) to cooperatively serve users without cell boundaries at the expense of …

The rapid growth of Internet of Things (IoT) dramatically increases power consumption of
wireless devices. Simultaneous wireless information and power transfer (SWIPT) is a …

This overview paper discusses the framework of sequential fractional programming for
energy efficiency maximization in future 5G networks. One of the main features of future …

Cell-free system is an efficient solution to eliminate inter-cell interference by serving users
without cell boundaries. To further improve the spectrum efficiency, in this letter, we consider …

In this paper, we investigate the fundamental tradeoff between energy efficiency (EE) and
delay for time-varying and interference-free wireless networks. We formulate the problem as …

Along with spectral efficiency (SE), energy efficiency (EE) is a key performance metric for the
design of 5G and beyond 5G (B5G) wireless networks. At the same time, infrastructure …

In this paper, we present a power allocation method for a distributed antenna system (DAS)
to maximize energy efficiency (EE), which is defined as the ratio of the transmission rate to …

In this paper, we propose a transmit covariance optimization method to maximize the energy
efficiency (EE) for a single-user distributed antenna system, where both the remote access …
