Full Duplex Wireless Communications for Cognitive Radio Networks
As a key in cognitive radio networks (CRNs), dynamic spectrum access needs to be carefully designed to minimize the interference and delay to the primary (licensed) users. One of the main challenges in dynamic spectrum access is to determine when the secondary (unlicensed) users can use the spectrum. In particular, when the secondary user is using the spectrum, if the primary user becomes activ...
متن کاملLeasing-Based Performance Analysis in Energy Harvesting Cognitive Radio Networks
In this paper, we consider an energy harvesting cognitive radio network (CRN), where both of primary user (PU) and secondary user (SU) are operating in time slotted mode, and the SU powered exclusively by the energy harvested from the radio signal of the PU. The SU can only perform either energy harvesting or data transmission due to the hardware limitation. In this case, the entire time-slot i...
متن کاملPerformance and Energy Efficiency of Cognitive Full-Duplex under Spectrum Sharing Constraints
In a cognitive radio context under spectrum sharing constraints, a secondary network may transmit concurrently with the primary one as long as the communication of this latter is not compromised. For such an operation, a maximum allowable interference level at the primary receiver is defined, and secondary users (SUs) should take into account this threshold during the transmission in order to a...
متن کاملBeamforming optimisation in energy harvesting cooperative full-duplex networks with self-energy recycling protocol
This paper considers the problem of beamforming optimization in an amplify-and-forward (AF) relaying cooperative network, in which the relay node harvests the energy from the radio-frequency (RF) signal. Based on the self-energy recycling relay protocol, we study the beamforming optimization problem. The formulated problem aims to maximize the achievable rate subject to the available transmitte...
