The ergodic resource allocation (ERA) problem for uplink transmission in underlay cognitive
radio networks (CRNs) is investigated. The objective is to maximize the ergodic sum-rate of …

We investigate the problem of power allocation to secondary users (SUs) in underlay
cognitive radio networks (CRNs), where the channel state information (CSI) pertaining to the …

A resource allocation task for the uplink of OFDMA-based cognitive radio (CR) systems is
considered. The weighted sum-rate is maximized over subcarrier assignment as well as …

In this paper, we investigate the energy consumption issue in cognitive radio (CR) networks.
We aim to maximize the energy efficiency of the CR network while considering practical …

This paper considers the problem of radio resource allocation in an orthogonal frequency-
division multiple access based cognitive radio (CR) network that opportunistically operates …

In this paper we study the resource allocation in multiuser orthogonal frequency division
multiplexing (OFDM)-based cognitive radio (CR) networks, where secondary users (SUs) …

A resource allocation problem for a cognitive radio base station (CR-BS) communicating
with multiple CR mobile stations (MSs) is considered in the downlink, which relies on …

We study the resource allocation (RA) problem in a multiuser OFDM-based cognitive radio
(CR) system for non-realtime (NRT) applications in which average user data rates are to be …

In this article, adaptive resource allocation (ARA) is investigated for multiple primary
networks based-cognitive radio networks under a more practical system model, where the …

A robust Ergodic Resource Allocation (ERA) scheme is proposed in this paper in the
framework of an orthogonal frequency division multiple access (OFDMA) based underlay …
