Performance analysis of CBSS for CR based 5G

Abstract

With the rapid and continuous growth of mobile users and services across the world, 5G is anticipated to be the next step in the development of the cellular network. The conceptualized architecture for 5G uses a dynamic spectrum sharing (DSS) approach to include a common spectrum resources that is shared by a multitude of varied network entities and systems. While this proposed solution would vitally enhance the entire efficiency of spectrum. In this situation, the unique function of spectrum sensing (SS) that belongs to the cognitive radio (CR) paradigm is recently being introduced as one of the primary facilitators for effective DSS with less interference. The dissemination of the testing criteria for the detection problem is examined in this paper to get the precise formulas for probability false alarm (Pf) and detection probability (Pd). The performance of the covariance detector can be evaluated by using pd and pf expressions. Finally, theoretical Pd, Pf expressions are verified with simulations.
