We examine the impact of limited channel knowledge on the secondary user (SU) in a
cognitive radio system. Under a minimum signal-to-interference noise ratio (SINR) constraint …

In this paper, we analyze the effect of maximum ratio combining (MRC) diversity on the
performance of cognitive radio systems, in which the cognitive user (CU) shares the same …

We propose transmit antenna selection with receive generalized selection combining in dual-
hop cognitive decode-and-forward relay networks with spectrum sharing for reliability …

Capacity of the cognitive radio network degrades due to the interference constraint from the
primary network. The secondary network capacity can be enhanced in a cost effective way …

We study the performance of a dual-hop cognitive radio network sharing the spectrum of a
primary network in an underlay fashion. In particular, the cognitive network consists of a …

We propose cognitive spectrum sharing with generalized selection combining (GSC) at the
secondary user (SU) in the presence of multiple primary transceivers with outdated channel …

Spectrum sharing cognitive radio aims to improve the spectrum efficiency via sharing the
spectrum band licensed to the primary user (PU) with the secondary user (SU) concurrently …

Capacity of the secondary network degrades due to the interference constraint from the
primary network. The secondary network capacity can be enhanced by means of spatial …

This paper investigates the performance of power limited Cognitive Radio system with
optimum combining at the cognitive user receiver under the influence of interference from …

We propose transmit antenna selection with receive generalized selection combining
(TAS/GSC) in dual-hop cognitive decode-and-forward (DF) relay networks for reliability …
