This paper presents a novel resource allocation framework for downlink transmissions in
MIMO-OFDMA based cognitive radio (CR) networks. In this literature, due to the coexistence …

In this paper, the resource allocation for MIMO-OFDMA based cognitive radio (CR) network
subject to primary user's (PU)'s constraints is considered. The optimal resource allocation …

Abstract In the opportunistic Cognitive Radio (CR) networks, the secondary users'(SU)
capacity is limited due to the need to avoid the primary users'(PUs) bands. The combination …

Due to their spectrum shaping capability and high adaptability, the multi-carrier systems are
considered as prime candidates for use in the Cognitive Radio (CR) networks. In these …

The computational complexity of resource allocation processes, in cognitive radio networks
(CRNs), is a major issue to be managed. Furthermore, the complicated solution of the …

Multi-carrier systems are one of the best candidates for applying in cognitive radio (CR)
networks because of the spectrum shaping and high adaptive capabilities. Since secondary …

This study investigates resource allocation problems for a point‐to‐point multi‐carrier
multiple‐input multiple‐output cognitive radio network. Different from conventional resource …

This paper proposes an efficient and low complexity power-loading algorithm for MIMO-
OFDM downlink based cognitive radio system that maximizes the sum rate of single …

In this paper, we consider the resource allocation problem in a Cognitive Radio (CR)
downlink system employing both Orthogonal Frequency Division Multiple Access (OFDMA) …
