The problem of subcarrier allocation (SA) and power allocation (PA) for both the downlink
and uplink of cognitive radio networks (CRNs) is studied. Two joint SA and PA schemes …

The resource allocation problem for orthogonal frequency-division multiple-access (OFDMA)-
based multicast cognitive radio networks is investigated under the spectral activities of …

Introducing orthogonal frequency division multiplexing (OFDM) into cognitive radio (CR) can
potentially increase the spectrum efficiency, but it also leads to further challenges for the …

In this paper, a Stackelberg game is built to model the joint power allocation of the primary
user (PU) network and the secondary user (SU) network hierarchically in orthogonal …

We consider OFDMA-based cognitive radio (CR) networks where multiple secondary users
(SUs) compete for the available sub-bands in the spectrum of multiple primary users (PUs) …

In this paper we develop a framework for resource allocation in a secondary spectrum
access scenario, where a group of cognitive radios (CR) access the resources of a primary …

This paper proposes a new Nash bargaining solution (NBS) based cooperative game-
theoretic scheduling framework for joint channel and power allocation in orthogonal …

Resource allocation with sensing-based interference price is considered for multi-users
cognitive radio (CR) network, in which the primary base station (PBS) controls the secondary …

Cognitive radio (CR) is proposed to improve frequency efficiency while avoiding interference
with licensed users. In this paper, we adopt a resource allocation (RA) algorithm to perform …

In this paper we have studied the subcarrier and optimal power allocation strategy for OFDM-
based cognitive radio (CR) networks. Firstly, in order to protect the primary user …
