Query: Exploring Green Interference Power for Wireless Information and Energy
  Transfer in the MISO Downlink   In this paper we propose a power-efficient transfer of information and
energy, where we exploit the constructive part of wireless interference as a
source of green useful signal power. Rather than suppressing interference as in
conventional schemes, we take advantage of constructive interference among
users, inherent in the downlink, as a source of both useful information and
wireless energy. Specifically, we propose a new precoding design that minimizes
the transmit power while guaranteeing the quality of service (QoS) and energy
harvesting constraints for generic phase shift keying modulated signals. The
QoS constraints are modified to accommodate constructive interference. We
derive a sub-optimal solution and a local optimum solution to the precoding
optimization problem. The proposed precoding reduces the transmit power
compared to conventional schemes, by adapting the constraints to accommodate
constructive interference as a source of useful signal power. Our simulation
results show significant power savings with the proposed data-aided precoding
compared to the conventional precoding.
