Resource allocation for OFDM-based multiuser cooperative underlay cognitive systems

Autor: Marwa Chami, Mylene Pischella, Didier Le Ruyet

Publikováno v: EURASIP Journal on Wireless Communications and Networking, Vol 2017, Iss 1, Pp 1-15 (2017)

Abstract This paper investigates the resource allocation problem for a multiuser underlay cognitive system where the secondary system is allowed to transmit and cooperate with the primary system. In this scenario, the secondary users are subject to t

International audience; We propose an Overlay network architecture for re- liable and QoS-aware interconnection between its nodes, without handling Internet routers and without tunneling overhead. The architecture is based on the SDN paradigm. We dem

In this paper, we propose a new full-duplex relay-assisted cognitive radio system model with an adaptive decoding algorithm at the secondary user, in order to maximize both primary and secondary achievable rates. We consider the uplink transmission a

Resource allocation with SIC under statistical CSI in multi-carrier based cognitive radio networks

Autor: Didier Le Ruyet, Marwa Chami, Mylene Pischella

Publikováno v: WCNC

In this paper, we study the problem of resource allocation for an opportunistic spectrum-sharing channel under the assumption of statistical channel state information (CSI). More specifically, we assume that statistical CSI of the channels between bo

Optimal power control for cooperative underlay cognitive system

Autor: Marwa Chami, Mylene Pischella, Didier Le Ruyet

Publikováno v: ISWCS

This paper proposes a new underlay cooperative cognitive radio system, where a paid cooperation between the primary and the secondary systems is allowed. We consider both decoding strategy at the secondary receiver and the power efficiency optimizati
