Spectrum occupancy models are very useful in cognitive radio designs. They can be used to
increase spectrum sensing accuracy for more reliable operation, to remove spectrum …

While dedicated spectrum occupancy monitoring provides vital information for frequency
planning and management, it usually cannot tell the common properties in spectrum …

When Hurricane Katrina hit the Gulf Coast of the United States in 2005, it severely damaged
the telecommunications infrastructure, isolating the area from the outside world. With all the …

The performance of systems using high frequency (HF) radio waves, such as over-the-
horizon radars (OTHR), can be strongly affected by external interferers at great distances …

The high frequency (HF) radio channel is highly variable and unpredictable. On the other
hand, being largely utilized around the globe, the HF spectrum is densely occupied …

This paper presents the development of Neural Network models to predict the likelihood of
interference experienced by Broadcast users in the HF spectrum (3-30 MHz). The models …

This paper presents an analysis of the characteristics of HF (1.6-30 MHz) spectral
occupancy and describes the development of neural network models to predict the …

A long-term joint UK–Swedish–German project has been undertaken on the measurement
and analysis of HF spectral occupancy over northern Europe. This has resulted in an …

While the dedicated spectrum occupancy monitoring provides vital information for frequency
planning and management, it usually cannot tell the common properties in spectrum …

This paper presents the application of Neural Networks as a means of optimising the
