Abstract: A method is provided for digital Simultaneous Information and Energy Transfer (SIET), comprising the steps of receiving a serial SIET analog signal, and converting the serial SIET analog signal received into a parallel SIET analog signal, extracting an analog information signal and an analog energy signal from the parallel SIET analog signal, performing analog-to-digital conversion on the analog information signal to obtain a digital information signal, and performing information demodulation, parallel-to-serial conversion and decoding on the digital information signal in digital domain, and pre-processing the analog energy signal in analog domain and storing the preprocessed analog energy signal. As the information signal is processed in the digital domain and the energy signal is processed in the analog domain, the energy in the SIET signal can be full collected in receiving side.

Abstract: A receiver is provided, wherein the receiver includes an antenna, a band pass filter and a frequency mixer electrically connected in sequence, and a local oscillator electrically connected with the frequency mixer, and further includes: a diplexer for separating and outputting high and low frequency components in a signal outputted by the frequency mixer; and a rectifying unit for converting the high frequency component outputted by the diplexer into direct current energy and storing the direct current energy in a storage battery. The diplexer introduced in the receiver separates a baseband signal and a carrier signal in the same path losslessly, respectively conducts information decoding and energy capture, implements simultaneous information and energy transfer, and does not need to change the present modulation technology, therefor having strong compatibility, being reasonable and simple in structure, and being easy to implement.
