In this paper, we study the optimal power allocation (OPA) for the two-way relay channel employing the analogue network coding (ANC) protocol in cognitive radio (CR) network. The OPA scheme is proposed by minimizing the weaker link's individual outage probability under the sum-power constraint and interference power threshold (IPT) constraints to the primary user (PU) in a Rayleigh fading channel environment. Particularly, for the purpose of accomplishing the power allocation more realistically… CONTINUE READING
