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 …

Multiple-input-multiple-output (MIMO) wireless systems are those that have multiple antenna
elements at both the transmitter and receiver. They were first investigated by computer …

Cognitive radio has emerged as an essential recipe for future high-capacity, high-coverage
multitier hierarchical networks. Securing data transmission in these networks is of the utmost …

We analyze the physical layer (PHY) security of a communication scheme consisting of a
multiple antenna transmitter with a single radio frequency (RF) chain using transmit antenna …

In this paper, we perform transmit antenna selection to improve the energy efficiency of large
scale multiple antenna systems. We derive a good approximation of the distribution of the …

Non-orthogonal multiple access (NOMA) is considered as a potential multiple access
technique for supporting massive number of devices with high spectral efficiency for the 5 G …

MIMO systems have been known to better the quality of service for wireless communication
systems. This book discusses emerging techniques in MIMO systems to reduce complexities …

In this paper, the performance of an uncoded multiple-input-multiple-output (MIMO) scheme
combining single transmit antenna selection and receiver maximal-ratio combining (the …

Multi-connectivity (MCo) is considered to be a key strategy for enabling reliable
transmissions and enhanced data rates in fifth-generation mobile networks, as it provides …

This paper considers a multiple-input multiple-output (MIMO) non-orthogonal multiple
access (NOMA) cognitive radio (CR) system with an unmanned aerial vehicle relay (UR). In …
