Traditional spectrum sensing methods require that a secondary user (SU) senses the spectrum at the beginning of each time slot. A closer look at the network activities of a cognitive radio network reveals that the access pattern of a primary user (PU) typically consists of a succession of transmission periods, alternating with idle periods, each of which lasts a number of time slots. Based on this...
Spectrum sensing is considered as the cornerstone of cognitive radio networks (CRNs), Sensing the wide band spectrum, however, may result in delays and reduce the efficiency of resource utilization. Spectrum prediction, therefore, has been proposed as a promising approach to overcome these shortcomings. Prediction of the channel occupancy, when feasible, provides adequate means for an SU to determine,...
