In this paper, we focus on the channel capacity analysis of a Cognitive Radio (CR) network
using two types of multicarrier communications: conventional Orthogonal Frequency …

The ever-increasing demand for precious radio spectrum along with the inefficient usage of
licensed band has led to the advent of the cognitive radio (CR) technology, which aims to …

We present a performance analysis between two different multi-carrier transmission
techniques: the OFDM, with cyclic prefix (CP) addition; and the FBMC (Filter-Bank …

Quick development of wireless communication makes the spectrum scarcity as a one of the
serious problems. Cognitive radio (CR) is considered to be one of the possible solutions to …

Cognitive Radio (CR) is widely considered as a novel approach to improve the utilization
efficiency of precious radio spectrum resource. Orthogonal Frequency Division Multiplexing …

Recent works in cognitive radio (CR) have suggested multicarrier communication based on
orthogonal frequency-division multiplexing (OFDM) for CR networks. In this paper, we …

Cognitive radio (CR) is one of the important paradigms proposed by FCC for improving the
spectrum utilization. To make agile spectrum resources allocation between the primary …

This paper presents an uplink radio resource allocation algorithm for multicarrier based
cognitive radio systems. The algorithm allocates the subcarriers to the users in the first step …
