Abstract

In this paper, a cognitive radio unit (CRU) model with a sequential scanning (S-scanning) scheme and cognitive perception ratio (CPR) metric under an elliptic radio environment for cognitive communications will be proposed. In this model, the real-time spectrum sensing characteristics are coordinated together with system parameters in temporal and frequency domains, e.g., scanning rate and framing processing time, for evaluating the performance of the CR communications under an elliptic operation scenario. High CPR value means high spectrum awareness, but low coexistence. Several intriguing numerical results are also illustrated to examine their interrelationships.
