As the complexities of wireless technologies increase, novel multidisciplinary approaches
for the spectrum sharing/management are required with inputs from the technology …

Inspired by recent results on information-theoretic security, we consider the transmission of
confidential messages over wireless networks, in which the legitimate communication …

Transmit-beamforming (TB) over multiple-input multiple-output (MIMO) fading channels
steers the transmit power in the receiver's direction, so as to maximize the output signal-to …

Since the trail-blazing paper of C. Shannon in 1948, channel capacity has been regarded as
the fundamental information-theoretic performance measure to predict the maximum …

In this chapter, we discuss on the physical insight and the various performance metrics of the
wireless channels environment in today's communications schemes. The availability and …

The author presents a unified treatment of this highly interdisciplinary topic to help define the
notion of cognitive radio. The book begins with addressing issues such as the fundamental …

In this paper, a framework is presented to analyze the performance of multiuser diversity
(MUD) in multiuser point-to-multipoint (PMP) MIMO systems with antenna selection. Based …

The distribution of the sum of non-negative random variables plays an essential role in the
performance analysis of diversity schemes for wireless communications over fading …

Optimization of the switching thresholds for constant-power adaptive five-mode M-ary
quadrature amplitude modulation (M-QAM) transmission with an amplify-and-forward (AF) …

This paper investigates the capacity of log-normal fading channels with receiver channel
state information. We provide a closed-form expression for the ergodic capacity of the log …
