Cognitive radio is an intelligent communication technology that allows secondary users to utilize licensed band opportunistically and helps in resolving the issue of spectrum scarcity. In spectrum sharing network, where the secondary user can communicate simultaneously along with primary user in the same frequency band, the main challenge to opportunistic radio spectrum access lies in finding balance between two conflicting goalsof satisfying performance requirements while minimizing interference. In this paper,the authors propose fuzzy logic transmit power control strategy which allows cognitive secondary user to achieve its required transmission rate and quality, while minimizing interference to primary user and other concurrent secondary user also applying compressive sensing to cognitive radio for performance enhancement by lowering the number of samples required to obtain the desired signal.
