摘要：
In this paper, cyclostationarity based cooperative spectrum sensing is presented to detect the idle bands and then locate the secondary users into these bands. The aim is to reduce the processing complexity with using a relay for transmission and spectrum sensing. As such, an optimum relay is selected to perform both cooperative communication and cyclostationarity based spectrum sensing. Performance of transmission, probability of detection, and probability of missing are presented via computer simulations. Results show that proposed jointly optimized relay selection scheme provides sufficient performance for both transmission and spectrum sensing.
