A multi-carrier broadband information energy simultaneous transmission system and receiving system

Abstract

The present invention relates to a multi-carrier broadband information energy simultaneous transmission system and a receiving system. The transmission system includes: a signal management control system, a baseband signal generation unit, a coding unit, a serial-to-parallel conversion unit, a mapping unit, a modulation unit, and a parallel-to-serial conversion unit ; Wherein, the signal management control system is used to dynamically pre-allocate the carrier, power, and spectrum of the information signal data flow and the energy signal data flow in the baseband signal based on the channel quality parameters and match the optimization algorithm, and generate a pre-allocation parameter set The baseband signal generation unit is used to generate corresponding information baseband signals and energy baseband signals according to the pre-allocated parameter set; adopting the information energy simultaneous transmission system of the present invention, sending opposite energy data while sending information data to the receiving end, It can provide enough energy for the receiver. In addition, the information signal and the energy signal are optimized through the optimization algorithm, which can not only improve the energy transmission efficiency but also increase the information transmission rate.
