Abstract
In this paper, we mainly study simultaneous wireless information and power transfer (SWIPT) for the multiuser resource allocation. All subcarriers are divided into two parts, part of which are for information decoding and another part are for energy harvesting. We optimize the subcarrier allocation and power allocation to maximize the energy that collected by all users under the target rate constraint. The original optimal problem is complicated, so it is hard to find the optimal solution directly. By transforming the primal problem, we finally solved the original problem by using the Lagrange dual method.
