摘要：
This paper investigates an underlay cognitive radio (CR) that extracts energy from radio-frequency signals of one primary user. We assume that both the wireless energy harvesting and the secondary transmission processes of the CR suffer Rayleigh block fading. Considering the intrinsic harvesting-transmitting tradeoff, we optimize the harvesting time and transmit power of the CR to minimize the outage probability of the secondary transmission, subject to the primary interference and the energy causality constraints. Numerical evaluation validates the correctness of this work.
