The design of opportunistic spectrum access (OSA) policy is a key technique of cognitive radio. In this paper, we consider a scenario that the secondary user can't sense full spectrum due to hardware constraints. In order to get higher transmission rate, we allow the secondary user sense multiple channels in a slot and group them together by channel bonding technique after detecting consecutive idle...
The core task of spectrum sensing in Cognitive Radio is to determine vacant spectrum timely and reliably. As the first cognitive radio based standard, IEEE 802.22 Wireless Regional Area Network aims to opportunistically utilize the underutilized VHF/UHF bands, therefore, reliably sensing incumbent signals on these bands arises as a key technique for IEEE 802.22 realization. Unfortunately, no algorithm...
