Abstract:

In this paper a cognitive radio network is considered where a licensed primary user and an energy harvesting secondary (cognitive) user co-exist, and relaying protocols are proposed where the cognitive user acts as a relay for the primary signal in return for spectrum access. We analyze two relaying paradigms, namely, time-splitting cooperative spectrum sharing (TS-CSS) relaying and power sharing cooperative spectrum sharing (PS-CSS) relaying and derive closed form expressions for the outage probabilities of both the users, assuming dual-hop decode and forward relaying under Nakagami-m fading model. Furthermore, it has been showed from obtained results that PS-CSS protocol outperforms TS-CSS protocol over a wide range of Signal to Noise ratio (SNRs).
