Abstract
The fact that cyclic delay diversity (CDD)-based single-carrier (SC) scheme increases the frequency diversity without entailing the receiver to be aware of the transmission strategy makes it to be a good candidate for achieving full diversity gain in cooperative systems. In this letter, we scrutinize the impact of CDD-SC scheme in the cognitive radio network (CRN) with a great aim of overcoming the channel estimation challenge as well as the signaling overhead in the CRN. More specifically, in virtue of order statistics, the closed-form expressions for outage probability and symbol error rate are derived under independent and identical distributed (i.i.d.) frequency-selective fading channel model. Our results divulge the diversity order of the proposed system to be mainly affected by the number of multipath components available in the CRN.
