Cognitive Radio under Conservative Regulatory Environments: Lessons Learned and near Term Options
Michael J. Marcus · 2010
In recent regulatory decisions, spectrum regulators have been very conservative in permitting use of cognitive radio systems requiring large "safety margins". This paper describes the nature of these safety margins and the factors that lead to them. New research that might counter such concerns is suggested. Cooperative approaches involving primary user systems that actively cooperate with cognitive users ad also suggested.
