Transmitting system and receiving system for multi-carrier broadband simultaneous information and energy transfer

摘要

A transmitting system and a receiving system for multi-carrier broadband simultaneous information and energy transfer are provided, the transmitting system comprising: a signal management control system, a baseband signal generating unit, an encoding unit, a serial-parallel conversion unit, a mapping unit, a modulation unit and a parallel-serial conversion unit. By adopting the transmitting system for simultaneous information and energy transfer, separate energy signals are transmitted simultaneously while the information signals are transmitted to the receiving end, and sufficient energy can be provided for the receiver. Besides, by optimizing information signal and energy signal through the optimization algorithm, not only the energy transfer efficiency but also the information transfer rate can be improved.
