Simultaneous digital information and energy transfer and reception method and system

Abstract

The invention relates to a simultaneous digital information and energy transfer and reception method and a simultaneous digital information and energy transfer and reception system. The reception method comprises the following steps: receiving serial simultaneous information and energy transfer analog signals, and converting the serial simultaneous information and energy transfer analog signals into parallel simultaneous information and energy transfer analog signals; separating information analog signals and energy analog signals among the parallel simultaneous information and energy transfer analog signals; carrying out analog-to-digital conversion on the information analog signals to obtain information digital signals, and carrying out information demodulation, parallel-serial conversion and decoding on the information digital signals in a digital domain; and preprocessing the energy analog signals in an analog domain and storing the energy analog signals in an energy storage unit. By adopting the method and the system, the information signals and the energy signals among the simultaneous digital information and energy transfer signals can be separated. The information signals are demodulated and decoded in the digital domain while the energy signals are processed in the analog domain, so that a receiver can fully collect the energy signals among the simultaneous transfer signals.

AI Technical Summary

Problems solved by technology

In the existing digital communication system, the signal for wireless transmission is an analog signal, and the digital receiving system needs to convert the received analog signal into a digital signal in the analog-to-digital conversion unit, which can improve communication reliability, but the energy of the original analog signal Not inherited, but dissipated in the form of heat

Therefore, if the existing digital receiving system is used to receive the simultaneous transmission signal, most of the energy contained in the energy signal will be dissipated, and the receiver cannot obtain enough energy from the received signal, resulting in power failure interrupt communication
