“…In this paper, a new relay based scheme for CR (cognitive radio) communication is proposed and analysed. By accurately designing the Beam forming (BF) weights at the relay node and taking into account the impact of imperfect CSI, we show that the proposal scheme outperforms the conventional scheme in term of secondary channel capacity and also circumvents the effect of imperfect CSI on the primary outage probability [9]. The work discussed the implementation of underlay cognitive radio network to enhance the reliability, capacity or power and coverage of the system.…”

Abstract. This work explores beam forming and two-way relaying to alleviate the dual issues of the spectrum congestion and spectrum under-utilization. These problems can be alleviated by the implementation of underlay cognitive radio networks. However, their reliability, capacity or power, and coverage depend on bi-directional or abbreviated as primaryto-secondary (P2S) and secondary-to-primary (S2P) interference constraints. This work makes of two-way relaying to improve these essential and paramount efficiencies, performance and effectiveness measures.
