摘要Abstract: The efficient utilization of underutilized spectrum is the main theme of current research.The Q-learning algorithm is used to detect the presence of primary signals and utilize the spectrum in the absence of primary signals.

Two main problems :
• failure to detect the presence of PU
• false detection of PU when user does not exist (enter into the domain).
