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

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

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
