In this paper we review the most peculiar and interesting information-theoretic and
communications features of fading channels. We first describe the statistical models of …

A simple idealized linear (and planar) uplink cellular multiple-access communication model,
where only adjacent cell interference is present and all signals may experience fading, is …

In future wireless multimedia networks, there will be a mixture of different traffic classes
which have their own maximum tolerable bit error rate (BER) requirements. In this paper, a …

We obtain the Shannon capacity region of the down-link (broadcast) channel in fading and
additive white Gaussian noise (AWGN) for time-division, frequency-division, and code …

This book is the result of several years of teaching and research at the Federal University of
Campina Grande, Federal University of Pernambuco, and Federal University of Bahia …

We study the information theoretic capacity of M-ary pulse position modulation (PPM) ultra-
wideband (UWB) communications for the multi-user channels. Under certain assumptions …

The spectral efficiency of a hybrid cellular direct-sequence/frequency hopping code-division
muItiple-access (DS/FH-CDMA) system operating in a Rayleigh-fading environment is …

Code-division multiple access (CDMA) has been proven to be one of the promising
mainstream multiaccessing techniques in future cellular mobile communication systems. A …

This article presents a mathematical modelling, using stochastic analysis, of the effect of an
interference buildup caused by a sudden increase in the number of users that access a …

The theoretically achievable average channel capacity (in the Shannon sense) per user of a
hybrid cellular direct sequence/fast frequency hopping code‐division multiple‐access …
