摘要：
This paper investigates resource allocation in a multi-user, multi-band and multi-antenna equipped wireless communication system, which is used for simultaneous wireless information and power transmission (SWIPT). The optimization problems of sum-rate over multiple sub-bands subject to the power spectral density requirement (PSDR) limit and the circuit power requirement (CPR) are studied in the case of two users, i.e., far-user (FU) and near-user (NU), and under 3 situations: 1) to maximize the global information sum-rate; 2) to maximize the information rate of far-user with higher priority; 3) to maximize the least of common throughput. Using convex optimization methods, the above 3 problems are solved. Simulation results are provided to demonstrate the presented solutions.
