Abstract
We considered a precoder used in wireless information transfer (WIT) and wireless power transfer (WPT) systems for multi-user multiple-input multiple-output (MIMO) simultaneous wireless information and power transfer (SWIPT) systems. We compare two representative linear precoders which are minimum mean square error (MMSE) and signal-to-leakage-and-noise ratio (SLNR) based precoders for data users and energy beamformer for energy users. The simulation results show that the rate-energy region of the considered precoder is weighed towards one side which is data rate side or harvested energy side according to power allocation between data users and energy users. Besides, when there are many energy users, controlling the direction of the data signal is important in the aspect of energy harvesting.
