Article.
Accés restringit per política de l'editorial
This paper proposes a methodology based on order statistics to study the energy-efficient (EE) power allocation for wireless communication transmitters. Water-filling power allocation maximizes the EE when transmitting and ...
Spectrum occupancy in realistic scenarios and duty cycle model for cognitive radio
(2010-04)
Article.
Accés obert
Article.
Accés obert
Most of the spectrum occupancy measurement campaigns
performed to the date in the context of cognitive radio
are based on measurements in outdoor high points such as building
roofs, balconies and towers. Although these ...

This letter presents a rule-based solution search
(RBSS) algorithm for self-optimization in a cellular network. It
improves the solution search process of classical optimization
methodologies by including a set of rules ...
Implementation of cognitive radio networks to evaluate spectrum management strategies in real-time
(2016-04-01)
Article.
Accés obert
Article.
Accés obert
This paper illustrates a Universal Software Radio Peripheral (USRP)-based real-time testbed that is able to evaluate different spectrum management solutions that exploit the Cognitive Radio (CR) paradigm. The main objective ...

Article.
Accés restringit per política de l'editorial
In this letter, a new hybrid technique to synthesize sparse linear arrays is proposed. This technique is based on the combination of two methods. As a first method, a deterministic synthesis algorithm is used to resolve ...
Enhancing satellite & terrestrial networks integration through NFV/SDN technologies
(2015-07-01)
Article.
Accés obert
Article.
Accés obert
NFV and SDN technologies can become key facilitators for the combination of terrestrial and satellite networks. Enabling NFV into the SatCom domain will provide operators with appropriate tools and interfaces in order to ...
