摘要：

Spectrum sensibility is the predominant function in CR designer to detect the spectrum holes of Primary radio, so it's astringent and complex task. The spectral sensor must have entire awareness about spectrum environment with a trivial delay and adequate complexity. The cyclostationarity of OFDM signals offer some statistics that will determine the status of the spectrum. Therefore, it's reliable at low SIN ratio. In this paper, CORDIC scheme is used to design a Spatial Sign Function (SSF) and complex exponential for Implementation of Cyclostationary Feature Detector. Therefore, the design complexity- can he minimized by reducing the number of multipliers. Also, the system efficiency can be improved. For simulation and testing, Quartus 15 is used for Altera high-speed Arria V GZ kit.
