Wireless communication plays a vital role in the success of railroad operations. This article describes an effort toward developing a railroad-specific cognitive radio (rail-CR) that can meet the needs of future wireless communication systems for railways by making positive train control (PTC) communication more interoperable, robust, reliable ...

2009 IEEE International Conference on Semantic Computing, 2009
This paper characterizes key semantics issues in shaping cognitive radio behavior to realize social contracts and business logic via cognitive radio behavioral semantics, with an immediate need for IEEE P1900.5 policy languages. The paper shows the current lack of consensus on the scope and needs of policy languages, tracing roots to differences among ...

Radio Environment Prediction for Cognitive Radio
2008 3rd International Conference on Cognitive Radio Oriented Wireless Networks and Communications (CrownCom 2008), 2008The evaluation and the prediction of the radio environment is one of the key issues to improve the cognitive radio. The prediction accuracy of the transmission capability in each wireless media will directly affect the performance of the transmission performance.

On cognitive processes in cognitive radio networks
Wireless Networks, 2013In this article we model the cognitive processes and evaluate their impact on the performance of cognitive radio networks (CRN). Operation of the cognitive radio nodes, can be characterized by two types of processes: communication processes such as packets transmission, and cognitive processes such as estimation of the network state and decision-making

Wireless Personal Communications, 2010
Both the cognitive radio (CR) and the fifth generation of cellular wireless standards (5G) are considered to be the future technologies: on one hand, CR offers the possibility to significantly increase the spectrum efficiency, by smart secondary users (CR users) using the free licensed users spectrum holes; on the other hand, the 5G implies the whole ...

Cognitive Satellite Terrestrial Radios
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010In this paper we present the concept of cognitive satellite terrestrial radios (CSTR) for hybrid satellite-terrestrial systems (HSTS). The cognitive radio (CR) technology is being motivated by the radio regulatory bodies for efficient utilization of the radio spectrum.

Deployment of Cognitive Radio in India
Wireless Personal Communications, 2014Cognitive radio is much talked as solution to limited spectrum resource. Provisions for deployment of cognitive radio have already been made in most of the EU countries, USA and Canada. It has not yet been introduced in India. This paper describes the frequency allocation for different services in Indian national frequency allocation plan.

Radio logicielle, radio cognitive
2013Il y a 20 ans déjà que la radio logicielle a été définie conceptuellement dans l’article fondateur de Joe Mitola III de 1995 sur la “software radio architecture” paru dans l’IEEE Communications Magazine. Comme c’est souvent le cas dans les secteurs technologiques, les militaires (DoD, Department of Defense des Etats-Unis) ont été précurseurs dans le ...
