Machine learning schemes can be employed in cognitive radio systems to intelligently locate the spectrum holes with some knowledge about the operating environment. In this paper, the authors formulate a variation of actor critic learning algorithm known as Continuous Actor Critic Learning Automaton (CACLA) and compare this scheme with actor critic Learning scheme and existing Q - learning scheme. Simulation results show that their CACLA scheme has lesser execution time and achieves higher throughput compared to other two schemes.
