Comments Off on Transmit Pre-coding for Interference Exploitation in the Underlay Cognitive Radio Z-channel
Posted in: IEEE 2017, MATLAB
Transmit Pre-coding for Interference Exploitation in the Underlay Cognitive Radio Z-channel Abstract: This paper introduces novel transmit precoding approaches for the cognitive radio (CR) Z-channel. The proposed transmission schemes exploit noncausal information about the interference at the secondary base station to redesign the CR precoding optimization problem. This is done with the objective to improve […]

Comments Off on Proactive Spectrum Sharing for SWIPT in MIMO Cognitive Radio Systems Using Antenna Switching Technique
Posted in: IEEE 2017, MATLAB
Proactive Spectrum Sharing for SWIPT in MIMO Cognitive Radio Systems Using Antenna Switching Technique Abstract: In this paper, we consider simultaneous wireless information and power transfer for spectrum sharing (SS) in a multiple-input multiple-output cognitive radio (CR) network. The secondary transmitter (ST) selects only one antenna, which maximizes the received signal-to-noise ratio at the secondary […]
