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 …

Analytical methods for finding moments of random Vandermonde matrices with entries on
the unit circle are developed. Vandermonde matrices play an important role in signal …

This paper addresses pilot-assisted channel estimation for wireless orthogonal frequency
division multiplexing (OFDM) systems with irregular pilot arrangements. Using nonuniform …

This paper centers on the limit eigenvalue distribution for random Vandermonde matrices
with unit magnitude complex entries. The phases of the entries are chosen independently …

While the efficiency of MIMO transmissions in a rich scattering environment has been
demonstrated, less is known about the situation where the fading matrix coefficients come …

The dramatic increase in the number and sensing capabilities of mobile devices is fostering
opportunistic sensing as a paramount data collection paradigm in smart cities. According to …

Wireless Sensor Networks are presented as devices for signal sampling and reconstruction.
Within this framework, the qualitative and quantitative influence of (i) signal granularity,(ii) …

Environmental monitoring is often performed through wireless sensor networks, by randomly
deploying sensor nodes over the geographical region of interest. Sensors sample a physical …

Random matrices are nowadays classical tools for modeling multiantenna wireless
channels. Scattering phenomena typical of cellular frequencies and channel reciprocity …

Different types of convolution operations involving large Vandermonde matrices are
considered. The convolutions parallel those of large Gaussian matrices and additive and …
