Optimal Transmission Schemes for Parallel and Fading Gaussian Broadcast Channels With an Energy Harvesting Rechargeable Transmitter
The authors consider an energy harvesting transmitter sending messages to two users over parallel and fading Gaussian broadcast channels. Energy required for communication arrives (is harvested) at the transmitter and a finite-capacity battery stores it before being consumed for transmission. Under off-line knowledge of energy arrival and channel fading variations, they obtain the trade-off between the performances of the users by characterizing the maximum departure region in a given interval. They first analyze the transmission with an energy harvesting transmitter over parallel broadcast channels.
