Resource Allocation for Secure MISO-NOMA Cognitive Radios Relying on SWIPT
Cognitive radio (CR) and non-orthogonal multiple access (NOMA) are two promising technologies in the next generation wireless communication systems. The security of a NOMA CR network (CRN) is important but lacks of study. In this paper, a multiple-input single-output NOMA CRN relying on simultaneous wireless information and power transfer is studied. In order to improve the security of both the...
متن کاملRobust Adaptive Beamforming in Cognitive Radio Networks
In this paper, we propose an adaptive non-intrusive cognitive radio network based on smart antenna technologies. The cognitive transmitter (CT), which is equipped with antenna array, first estimates and tracks the composite steering vectors of each primary (licensed) user. In what follows, CT forms transmit beamforming to place nulls to primary receivers (PR) based on the estimated spatial sign...
متن کاملArtificial Noise Aided Secure Cognitive Beamforming for Cooperative MISO-NOMA Using SWIPT
Cognitive radio (CR) and non-orthogonal multiple access (NOMA) have been deemed two promising technologies due to their potential to achieve high spectral efficiency and massive connectivity. This paper studies a multiple-input singleoutput NOMA CR network relying on simultaneous wireless information and power transfer (SWIPT) conceived for supporting a massive population of power limited batte...
متن کاملSpectrum Sharing in Cognitive Radio Based on Robust Adaptive Beamforming
Cognitive radio is an emerging technology in wireless communication for efficient utilization of the underutilized spectrum and alleviates the spectrum scarcity. Smart antennas efficiently utilize the spectrum in cognitive radio networks. In this paper, the cognitive system consists of the secondary user, which is equipped with the multiple antennas in the form of the array and follows the stee...
متن کاملRobust Weighted Sum Harvested Energy Maximization for SWIPT Cognitive Radio Networks Based on Particle Swarm Optimization
In this paper, we consider multiuser simultaneous wireless information and power transfer (SWIPT) for cognitive radio systems where a secondary transmitter (ST) with an antenna array provides information and energy to multiple single-antenna secondary receivers (SRs) equipped with a power splitting (PS) receiving scheme when multiple primary users (PUs) exist. The main objective of the paper is...
