摘要：

Energy detection based non-cooperative and cooperative spectrum sensing methods are considered in this paper for a full-duplex (FD) cognitive radio (CR) network. The CRs are assumed to be mobile and the wireless channels between CR(s) and primary transmitter (PT) are considered as time-selective. Such time-selective channels are characterized using Nakagami-m fading. The effect of mobility is captured using Jake's model. The expressions for the false alarm and detection probabilities are derived under the influence of Nakagami-m distributed residual self-interference (RSI). Moreover, with double threshold at CR, we analyze the receiver operating characteristics (ROC), area under ROC curve (AUC) and the total error rate performances. All the analytical results are validated through Monte Carlo simulations. (C) 2019 Elsevier GmbH. All rights reserved.
