METHOD FOR BEAMFORMING Design IN Simultaneous WIRELESS INFORMATION AND POWER TRANSFER SYSTEM RECORDING MEDIUM AND APPARATUS FOR PERFORMING THE METHOD

摘要

A method for generating beamforming in a wireless information and power simultaneous transmission system, and an apparatus for performing the same, (here, Is a natural number) derives a transmission signal transmitted from a base station having antennas to multiple information users and multiple energy users, and i (where m is a natural number) is included in the cell i (where i is a natural number) The noise ratio (SINR) of each i (where i is a natural number) th information is derived by using the noise power of the information user, and j (here, j is a natural number) included in the cell m (where m is a natural number) The energy harvesting amount of the second energy user may be derived, and beamforming may be generated using the power of the transmission signal at the base station and the total energy yield of the plurality of energy users receiving the transmission signal from the base station. Accordingly, it is possible to improve the effect of minimizing the transmission power of the base station while satisfying the quality of service (QoS) of the information user and the transmission power limitation while maximizing the energy yield of the energy users.
