Cognitive Radio (CR) is a dynamic spectrum access approach, in which unlicensed users
(or secondary users, SUs) exploit the underutilized channels (or white spaces) owned by the …

The construction of smart railways and railway informatization urgently needs the support of
Internet of Things (IoT) technology. IoT services will provide comprehensive guarantees for …

Aim: We set out to investigate the benefit of the “memory” of long short term memory (LSTM)
networks in predicting spectrum occupancy in multiple time horizons in Land Mobile Radio …

The radio spectrum scarcity represents a major challenge for wireless communication
systems, this is a result of allocating radio spectrum statically with exclusive assignment …

In cognitive radio networks (CRNs), secondary users (SUs) are permitted to use the
available spectrum in opportunity ways to optimize spectrum utilization. As legal spectrum …

Aim: We seek to assess the performance of time delay neural networks (TDNN), one of the
topologies designed for time series prediction, to characterize spectrum occupancy in …
