Spectrum Sensing in Non-Time-Slotted Full-Duplex Cognitive Radio Networks

  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.
