Time series arima model of spectrum occupancy for cognitive radio

While the dedicated spectrum occupancy monitoring provides vital information for frequency planning and management, it usually cannot tell the common properties in spectrum occupancy. As a complement, the models approach can be used to describe and summarize the occupancy situations under similar conditions. Time series analysis has been applied to modelling the radio spectrum occupancy. This paper categorises different time series models to different occupancy patterns. Occupancy analysis of the global system for mobile communications (GSM) band is given as an example.
