The cognitive radio network (CRN) is considered as one of the most important technologies that can allow the different users work as the same spectrum by different priorities. This paper proposes new methods and solutions to implement and performance analysis of work the WiMAX system within the spectrum of digital television broadcasting terrestrial through the cognitive radio network under various conditioning and types of modulation. Also, this paper explains and analyze the mechanism in which the cognitive radio works. Finally will be designed a prototype device simulate work the WiMAX system as a secondary user in digital TV broadcasting through the cognitive radio techniques.
