Abstract
Wireless technology plays a significant role in the national economy. The fast growing wireless devices, wireless traffic, and wireless applications create an unprecedented demand to radio spectrum. However, the radio spectrum has become a scarce resource due to the wasteful static spectrum allocation policy. On the other hand, the licensed spectrum has been found significantly underutilized. As a result, the ever-increasing spectrum demand and the exhausting spectrum supply become the driving force for the recent extensive research on efficient spectrum sharing. In this chapter, we discuss such driving force for spectrum sharing research and the enabling technology–cognitive radio.
