摘要: The rapid growth of wireless communication system has put pressure on radio spectrum usage. Due to the widely used fixed access, utilization is very low. In order overcome this problem, cognitive (CR), which leads way for dynamic access capability necessary. CR listens channel and enables unused primary user (PU). detection decision would be done by either a single secondary (SU) or multiple SUs cooperating with each other.
