Shu-Ching Chen,R. L. Kashyap,Arif Ghafoorng. In the initial setup phase that the CR users are performing spectrum sensing, idle communication channels without the licensed user signal have not been well identified and the reporting bandwidth is quite limited. In this chapter, bandwidth-efficient cooperative spectrum sensing in a multiuser

Such communications are essential for efficient and coordinated rescue and recovery missions in the aftermath of natural and man-made disasters. The envisioned paradigm differs from the traditional dynamic spectrum access paradigm of higher priority for licensed incumbent user

CR devices will be capable of adapt themselves to the environment and frequency band of interest providing reliable communication anywhere and anytime. The methods used by CR devices to detect the available spectrum are grouped in spe

We study the cognitive receiver structure which can recover the desired signal in the presence of interference, which we call signal separation. A path for better signal separation capability for resource efficiency, in order to utilize the ele

Simone Santini,Alexandra Dumitrescusimultaneous users while reducing interferences among users. In cognitive radio networks, this problem is referred to as the spectrum allocation problem, and is shown to be NP-Hard. This chapter studies the use of evolutionary algorithms to solve the spectrum allocation problem in cognitive radio ne
