  • Cognitive architecture and system solutions to offload LTE networks in TVWS

    Mange, G. (Geneviève); Celentano, U. (Ulrico); Lehne, P. H. (Per H.); , T. T. (Terje Tjeltas); López-Benítez, M. (Miguel) (2013)
    Projects: EC | QOSMOS (248454)
    Abstract This paper presents an application of cognitive radio system concepts for the off-loading operation of LTE networks by the opportunistic use of TV whitespace (TVWS). A flexible functional architecture based on two cognitive managers for spectrum management and resource management respectively, and developed for various mobile scenarios, is mapped to the LTE network architecture. Corresponding system solutions for incumbent protection and quality of service management (including s...

    Cognitive resource management for QoS support in mobile opportunistic communications

    Mange, G. (Geneviève); Rosik, C. (Christophe); Leveil, S. (Stéphanie); Celentano, U. (Ulrico); Durowoju, O. (Olasunkanmi); Arshad, K. (Kamran) (2011)
    Projects: EC | QOSMOS (248454)
    Abstract Optimizing the Quality of Service (QoS) support, providing seamless mobility and ensuring the protection of incumbent users are some of the challenges that arise when the radio spectrum is accessed in an opportunistic way. The functional concept of Cognitive Resource Manager (CRM) is presented providing cognition of the environment to optimize the allocation and exploitation of radio resources, to improve the access to these resources and to ensure mobility control in the opportu...

    Maximum outage capacity in dense indoor femtocell networks with joint energy and spectrum utilization

    Ko, Y; Moessner, K (2012)
    Projects: EC | QOSMOS (248454)
    We consider a multiple femtocell deployment in a small area which shares spectrum with the underlaid macrocell. We design a joint energy and radio spectrum scheme which aims not only for co—existence with the macrocell, but also for an energy—efficient implementation of the multi—femtocells. Particularly, aggregate energy usage on dense femtocell channels is formulated taking into account the cost of both the spectrum and energy usage. We investigate an energy-and-spectral efficient approach ...

    Resource management of centrally controlled cognitive radio networks

    Leveil, S. (Stephanie); Le Martret, C. J. (Christophe J.); Anouar, H. (Hicham); Arshad, K. (Kamran); , T. Z. (Talha Zahir); Bito, J. (János); Celentano, U. (Ulrico); Mange, G. (Geneviève); Rico, J. (Juan); Medela, A. (Arturo) (2012)
    Projects: EC | QOSMOS (248454)
    Abstract The realization of cognitive radio networks is a key solution to meet the raising expectations for high data rates and quality of service in mobile communications. This implies the design of a two-fold cognitive manager for resource management (CM-RM), to manage an opportunistic use of the whitespaces as introduced in this paper, and for Spectrum Management (CM-SM). The proposed CM-RM has been designed to be applicable to all kinds of control topologies (centralised/distributed)....

    Modulation Schemes for Cognitive Radio in White Spaces

    Kollar, Zs.; Horvath, P. (2010)
    Projects: EC | QOSMOS (248454)
    In this paper we give an overview and a comparison of the possible waveforms for white space applications. Four physical layer schemes for cognitive radio are selected for study: Orthogonal Frequency Division Multiplexing (OFDM), DFT-Spread OFDM (DFTS-OFDM), Constant Envelope OFDM (CE-OFDM) and Filter Bank Multicarrier (FBMC). The comparison is mainly based on the side effects of various non-ideal analog components (power amplifier, local oscillator) and residual synchronization errors such a...
