Abstract

In order to improve the spectral efficiency of a cognitive radio (CR) network and consider the asynchronism between the primary and secondary networks, this paper investigates a full-duplex (FD) non-time-slotted CR system based on the multi-antenna energy detection. The secondary transmitter with the FD technique can perform spectrum sensing and data transmission simultaneously. Firstly, the closed-form expressions of the probabilities of false alarm and missed detection are derived based on the proposed system with multiple sensing antennas. Secondly, the total error rate performance of the system is investigated in order to consider the benefits of the primary and secondary users concurrently. Meanwhile, the optimal decision threshold pair is investigated to minimize the total error rate of the system. Furthermore, the derived expressions in this paper are verified by simulation results and the obtained optimal decision threshold pairs achieve the minimum total error rates.
