Abstract :
For cooperative spectrum sensing, multiple secondary users are required to deliver their local decisions to a fusion centre through a report channel. A resource-efficient transmission technique for the report channel is presented, which can significantly reduce the time or frequency resource needed for transmission by simultaneously transmitting the local decisions.
