The energy of nodes except source node can be obtained by energy harvesting and all the UAV relay nodes transmitted signals via power splitting. Under the advance of non-static channel, the information user nodes were configured with multiple antennas and adopted max ratio combination (MRC). Based on the optimization criterion of energy efficiency maximization, the analytical solution of the optimal power allocation scheme for energy harvested and information transmission of multi-user two-UAV relay system was derived in detail. Since the optimization problem was a non-convex problem, this paper adopted the high signal-to-noise ratio approximation method and the power splitting method to realize the closed-form solution expression. The optimal solution of the objective function subjected with constraints can be obtained by Lagrangian algorithm and Lambert W function. Finally, the proposed algorithms and theoretical analysis are verified by simulations.<\/jats:p>","DOI":"10.1186\/s13638-019-1598-7","type":"journal-article","created":{"date-parts":[[2019,12,19]],"date-time":"2019-12-19T09:05:10Z","timestamp":1576746310000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Energy harvesting and information transmission scheme with UAV relay cooperation"],"prefix":"10.1186","volume":"2019","author":[{"given":"Baofeng","family":"Ji","sequence":"first","affiliation":[]},{"given":"Zhenzhen","family":"Chen","sequence":"additional","affiliation":[]},{"given":"Yuqi","family":"Li","sequence":"additional","affiliation":[]},{"given":"Sudan","family":"Chen","sequence":"additional","affiliation":[]},{"given":"Guoqiang","family":"Zheng","sequence":"additional","affiliation":[]},{"given":"Hong","family":"Wen","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2019,12,19]]},"reference":[{"issue":"5","key":"1598_CR1","doi-asserted-by":"publisher","first-page":"1707","DOI":"10.1109\/JIOT.2017.2717853","volume":"4","author":"X.
