For more information, see http://creativecommons.org/licenses/by/3.0/ abstract: This letter considers the multiple-input single-output (MISO) broadcast system for simultaneous wireless information and power transfer (SWIPT) using receiver power splitting and aims to optimize jointly the beamforming vectors and the power splitting ratios for minimizing the transmit power of the base station (BS) subject to the individual signal-to-interference-plus-noise ratio (SINR) and the energy-harvesting constraints at the mobile stations (MSs). However, the CSI is assumed imperfect but has a deterministic uncertainty region. Unlike existing attempts that resort to iterations guided by semidefinite relaxation (SDR), we propose a reverse convex nonsmooth optimization algorithm, which provides the near-optimal rank-one solution. date: 2016-01-01 date_type: published official_url: http://dx.doi.org/10.1109/LCOMM.2015.2498928 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1108271 doi: 10.1109/LCOMM.2015.2498928 lyricists_name: Khandaker, Muhammad lyricists_name: Liao, Jialing lyricists_name: Wong, Kai-Kit lyricists_id: MRAKH50 lyricists_id: JLIAO60 lyricists_id: KWONG98 actors_name: Barczynska, Patrycja actors_id: PBARC91 actors_role: owner full_text_status: public publication: IEEE Communications Letters volume: 20 number: 1 pagerange: 181-184 citation: Liao, J; Khandaker, MRA; Wong, K-K; (2016) Robust Power-Splitting SWIPT Beamforming for Broadcast Channels.
