Optimal Transmit Strategy for Multi-User MIMO WPT Systems With Non-Linear Energy Harvesters
Optimal Transmit Strategy for Multi-User MIMO WPT Systems With Non-Linear Energy Harvesters
In this paper, we study multi-user multi-antenna wireless power transfer (WPT) systems, where each antenna at the energy harvesting (EH) nodes is connected to a dedicated non-linear rectifier. We propose optimal transmit strategies which maximize a weighted sum of the average harvested powers at the EH nodes subject to a …
