摘要
Abstract
In this paper,energy harvesting technique and cooperative relaying technique are introduced into the cognitive radio network,and a cooperation scenario in which the secondary users as the relay node help primary users forward the data is studied.Then a optimal energy harvesting algorithm about time and power allocation is proposed based on Decode-and-forward mode.Simulation results show that compared with direct transmission,the proposed scheme not only reduces the outage probability of primary users and increases the secondary users' transmission rate,but also saves the network transmission energy and prolongs the life of the network.关键词
