Abstract
A system and method for cooperative spectrum sensing in cognitive radio (CR) systems is provided. A method for CR user operation includes coordinating with partner CR users to share spectrum sensing information, combining spectrum sensing information from partner CR users, and determining if a transmission opportunity exists based on the combined spectrum sensing information. The method also includes transmitting a message to a CR user if the transmission opportunity exists, and storing the message if the transmission opportunity does not exist.
