Performance Analysis of Full-Duplex Spectrum Sharing Networks under Peak Interference Power and Peak Transmit Power Constraints

摘要

In order to effectively solve the problem of spectrum shortage, cognitive radio and full duplex have been proposed and widely studied in recent year. In this paper, we integrate cognitive radio and full duplex technology, propose a full-duplex (FD) spectrum sharing cognitive radio networks, where both cognitive users are equipped with dual antennas, one of which is used to receive signals, and the other is used to transmit signals at the same time and frequency. In addition, we also analysis the ergodic sum capacity and the outage probability based on our proposed FD spectrum sharing cognitive radio networks. Simulations results validate that, our proposed FD spectrum sharing cognitive radio networks obtains better performance than the conventional spectrum sharing cognitive radio networks.
