Abstract EN
Accessibility to remote users in dynamic environment, high spectrum utilization, and no spectrum purchase make Cognitive Radio (CR) a feasible solution of wireless communications in the Internet of Things (IoT).
Reliable spectrum sensing becomes the prerequisite for the establishment of communication between IoT-capable objects.
Considering the application environment, spectrum sensing not only has to cope with man-made impulsive noises but also needs to overcome noise fluctuations.
In this paper, we study the Fractional Lower Order Moments (FLOM) based spectrum sensing method under Middleton Class A noise and incorporate a Noise Power Estimation (NPE) module into the sensing system to deal with the issue of noise uncertainty.
Moreover, the NPE process does not need noise-only samples.
The analytical expressions of the probabilities of detection and the probability of false alarm are derived.
The impact on sensing performance of the parameters of the NPE module is also analyzed.
The theoretical analysis and simulation results show that our proposed sensing method achieves a satisfactory performance at low SNR.
