This letter propose a novel scheme for cognitive macro/femtocell downlink coordinated
multipoint (CoMP) transmission to improve the capacity of femtocell without affecting the …

The structures of buildings in cities are complex and diverse, and traditional cellular
networks cannot achieve full coverage of indoor networks. To meet the needs of fire …

In past decades, cellular networks have raised the usage of spectrum resources due to the
victory of mobile broadband services. Mobile devices create massive data than ever before …

The cognitive femtocell network (CFN) integrated with cognitive radio-enabled technology
has emerged as one of the promising solutions to improve wireless broadband coverage in …

This paper presents a new method for computing discrete polynomial transforms. The
method is shown for the Hermite, binomial, and Laguerre transforms. The new method …

A Long Term Evolution-Frequency Division Duplexing (LTE-FDD) small cell is one of the
promising solutions for improving service quality and data rate in both the uplink and …

In cognitive radio networks, cooperative spectrum sensing (SS) between cognitive users can
improve the detection performance, reduce the testing time. However, a large amount of …

In this paper, we propose an optimal power allocation scheme in an uplink two-tier
heterogeneous cognitive network with non-orthogonal multiple access (NOMA). Secondary …

Cognitive radio (CR) is often described as a context-intelligent radio, capable of changing
the transmit parameters dynamically based on the interaction with the environment it …

Mobile traffic in cellular based networks is increasing exponentially, mainly due to the use of
data intensive services like video. One effective way to cope with these demands is to …
