In millimeter-wave (mmWave) systems, antenna architecture limitations make it difficult to
apply conventional fully digital precoding techniques but call for low-cost analog radio …

The spectrum efficiency (SE) and security of the secondary users (SUs) in the cognitive radio
networks (CRNs) have become two main issues due to the limitation interference to the …

This paper studies beamforming techniques for energy efficiency maximization (EEmax) in
multiuser multiple-input single-output (MISO) downlink system. For this challenging …

We study the problem of joint load balancing and interference mitigation in heterogeneous
networks in which massive multiple-input multiple-output macro cell base station (BS) …

Wireless sensor networks are applied in different domains such as agriculture, military,
healthcare, and defense. The most critical issue in wireless sensor networks is achieving …

Owing to severe path loss and unreliable transmission over a long distance at higher
frequency bands, this paper investigates the problem of path selection and rate allocation for …

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 consider the problem of joint beam selection and link activation across a
set of communication pairs to effectively control the interference between communication …

This paper aims at guaranteeing the achievable energy efficiency (EE) fairness in a multicell
multiuser multiple-input single-output downlink system. The design objective is to maximize …

This paper lists in alphabetical order by the name of the first author, 532 papers dealing with
fractional programming and its applications. This covers mainly the period 2012–2015 but it …
