Conference paper
Part of the Lecture Notes in Networks and Systems book series (LNNS, volume 5)

Abstract

In this chapter, the main goal is to enhance the energy efficient (EE) data transmission for an optimum value of sensing time in Amplify-and-forward   (AF) relay assisted cognitive radio network. Performance of the system has been studied in standard optimization framework under the constraints imposed on probability of detection threshold and the limitation of total power budget. Based on the mathematical model, analytical output is shown for various system parameters like, false alarm probability, throughput and energy efficiency. Furthermore, such evaluation illustrates the existence of an optimal sensing time, which improves the energy efficiency of the system.
