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

Cognitive Radio has been recognized as a promising way to improve spectrum efficiency of
wireless communications by exploiting under-utilized licensed spectrum in temporal …

Understand the fundamentals of wireless and MIMO communication with this accessible and
comprehensive text. Viewing the subject through an information theory lens, but also …

In this paper, we study a probabilistically robust transmit optimization problem under
imperfect channel state information (CSI) at the transmitter and under the multiuser multiple …

The full diversity gain provided by a multi-antenna channel can be achieved by transmit
beamforming and receive combining. This requires the knowledge of channel state …

In this paper, the situation in which a receiver has to execute a task from a quantized version
of the information source of interest is considered. The task is modeled by the minimization …

Given a multiple-input multiple-output (MIMO) channel, feedback from the receiver can be
used to specify a transmit precoding matrix, which selectively activates the strongest channel …

This paper investigates the problem of transmit beamforming in multiple-antenna spatial
multiplexing (SM) systems employing a finite-rate feedback channel. Assuming a fixed …

We consider multi-input multi-output (MIMO) transmit beamforming under the uniform
elemental power constraint. This is a nonconvex optimization problem, and it is usually …

This paper is on quantized beamforming in wireless amplify-and-forward (AF) relay
networks. We use the generalized Lloyd algorithm (GLA) to design the quantizer of the …
