Design of a robust Cognitive Control Channel for Cognitive Radio Networks based on Ultra Wideband pulse shaped signal

In collaborative Cognitive Radio Networks (CRN), Cognitive Radio (CR) nodes exchange information to perform the cognitive radio functions. The exchange of information in collaborative CRN is usually based on a Cognitive Control Channel (CCC). CCC can be classified in in-band channel or out-of-band channel. An Out-of-band CCC channel is a CCC, which uses a specific spectrum band In this paper, the authors propose the design of an out-of-band CCC based on an Ultra Wideband pulse shaped signal, which can mitigates some of the described challenges. The proposed design is particularly resilient to harmful interference and it is able to adapt its spectrum occupation to the primary wireless services present in the area. We define the requirements for the CCC and we provide simulation results to validate the design of the CCC against such requirements.
