Throughput maximization-based optimal power allocation for energy-harvesting cognitive radio networks with multiusers

Abstract An optimal power allocation (OPA) policy for orthogonal frequency division multiplexing (OFDM)-based cognitive radio networks (CRNs) using underlay spectrum access model is presented under multiple secondary users (SUs) with energy harvesting (EH).The proposed algorithm can allocate transmission power to each SU on each subcarrier with pom
