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