Dynamic Spectrum Access Using the Interference Temperature Model
Source: University of Maryland
To combat spectral overcrowding, the FCC investigated new ways to manage RF resources. The idea was to let people use licensed frequencies, provided they can guarantee interference perceived by the primary license holders will be minimal. With advances in software and cognitive radio, practical ways of doing this are on the horizon. In 2003 the FCC released a memorandum seeking comment on the interference temperature model for controlling spectrum use. Analyzing the viability of this model and developing a medium access protocol around it are the main goals of this paper. A model consisting of interference sources, primary licensed users, and secondary unlicensed users is modeled stochastically.
