In a wireless communication medium, the received signal envelope fluctuates randomly due
to the scattering nature of these channels. This paper is intended to present a …

In this letter, we consider a single-input multiple-output cognitive wiretap system over
generalized-K channels, where the eavesdropper overhears the transmission from the …

In this study, the secrecy performance of the classic Wyner's wiretap model over generalised‐
K fading channels is studied. The closed‐form expressions for the average secrecy capacity …

We consider a general selection-diversity scheme in which the kth best link is selected from
a number of links. We use extreme value theory to derive simple closed-form asymptotic …

In this paper, the effects of interference on composite fading environments, where multipath
fading coexists with shadowing, are investigated. Based on some mathematical convenient …

In this paper, a novel GPS-assisted grou** scheme is proposed to reduce the operational
cost of cognitive radio networks with femtocells. This scheme allows the cognitive base …

We analyze the asymptotic average throughput of a multiuser diversity (MD) scheme, in the
limit of large number of users, for free space optical (FSO) communication systems over a …

In this dissertation we investigate the performance of various wireless communication
systems that feature selection of the k-th best link from a number of links. We first consider …

In this paper the performance of a cooperative communication system operating over a
composite fading environment and is also subject to interference is investigated. More …

In this paper, we consider the scenario of N collocated users communicating over Free-
Space Optical (FSO) channels. We propose a novel cooperation scheme where the users …
