Simultaneous Wireless Information and Power Transfer in Multi-User Interference SISO System
In this paper, we study simultaneous wireless information and power transfer (SWIPT) in a multi- user interference single-input single-output (SISO) system. We first solve the ergodic rate optimization problem theoretically and derive the PS scheme and the TS scheme to obtain the optimal strategy of getting maximum ergodic capacity while harvesting sufficient energy to ensure receiver circuit working. The "rate-energy (R-E)" regions of the proposed schemes are derived. Then we compare the R- E regions of multi-user interference system with that of a noninterference channel. Finally we analyze R-E regions of multi-user interference SISO system with different interference intensities to show the influence of the interference, which is useful for user deployment and management.
