摘要：
Compared with conventional cognitive radio networks (CRNs), the efficiency can be improved if secondary users (SUs) have full duplex (FD) communication capabilities. We discuss FD spectrum sensing in non-time-slotted CRNs and study two work modes of SUs, transmitting-sensing (TS) mode and transmitting-receiving (TR) mode. SUs work alternately in two modes. In such a context, we analyze the sensing performance, probabilities of detection and false-alarm, and the SU throughput. An optimal time allocation strategy between TS and TR is proposed. And closed-form expressions of the allocation proportion of TR and TS are provided respectively, as with the detection and false-alarm probabilities. Numerical and simulation results have proved that our strategy can achieve much better performance.
