Spectral Efficiency of Energy Harvesting Random Cognitive Radio Networks in Dual-slope Model

Abstract

This research article evaluates the performance of an energy harvesting random cognitive radio networkemploying a dual-slope path-loss model in terms of spectral efficiency. It derives the mathematical expression of spectral efficiency by means of stochastic geometry for secondary receivers present in the network in active mode. The numerical result highlights a rise in the efficiency by 20.7% for an increase of 1 dBm in transmit power at a power splitting ratio of 0.5.
