It is now well known that employing channel adaptive signaling in wireless communication
systems can yield large improvements in almost any performance metric. Unfortunately …

The present article carries out a review of MIMO-based techniques that have been recently
proposed for satellite communications. Due to the plethora of MIMO interpretations in …

The past decade has seen many advances in physical layer wireless communication theory
and their implementation in wireless systems. This textbook takes a unified view of the …

Wireless technology is a truly revolutionary paradigm shift, enabling multimedia
communications between people and devices from any location. It also underpins exciting …

Mobile users' data rate and quality of service are limited by the fact that, within the duration
of any given call, they experience severe variations in signal attenuation, thereby …

We provide an overview of the extensive results on the Shannon capacity of single-user and
multiuser multiple-input multiple-output (MIMO) channels. Although enormous capacity …

Multiple transmit antennas in a downlink channel can provide tremendous capacity (ie,
multiplexing) gains, even when receivers have only single antennas. However, receiver and …

Transmit beamforming and receive combining are simple methods for exploiting the
significant diversity that is available in multiple-input multiple-output (MIMO) wireless …

Multiple-input multiple-output (MIMO) technology constitutes a breakthrough in the design of
wireless communications systems, and is already at the core of several wireless standards …

The tradeoff of spectral efficiency (b/s/Hz) versus energy-per-information bit is the key
measure of channel capacity in the wideband power-limited regime. This paper finds the …
