Optimal MIMO broadcasting over time-varying wireless channels for energy harvesting transmitter with non-ideal circuit power

摘要

We develop a novel approach to optimal broadcast scheduling over time-varying channels for an energy harvesting transmitter with finite-capacity battery and non-ideal circuit power consumption. Relying on the convex optimization tools, a low-complexity algorithm is proposed to obtain the optimal transmission policy that maximizes the weighted sum-throughput for multi-input multi-output (MIMO) broadcast channels. Our approach provides the optimal benchmark to all the practical schemes for energy harvesting powered broadcasting with non-ideal circuit power.
