Abstract

Abstract

In recent years, time-modulated array has aroused much attention due to its superior performance on vector control. Based on the time modulation method, a type of reconfigurable backscattering communication system based on time modulation technique is proposed in this paper. In backscattering node of the proposed system, multiple digital modulation symbols are mapped into the harmonic component of the control waveforms. The scattering or absorbing states of the incoming wave from the base station are then controlled by the designed waveforms. After the receiver samples the backscattering signal and extracts the control waveforms, the digital modulation symbols transmitted from the backscattering node can be recovered from the harmonic component with the Fourier transform. Simulation results demonstrate the performance of the harmonic demodulation methods and consistency with the theoretical values. Meanwhile, the reconfigurable backscattering transmitting experiments based on amplitude, phase shift keying and quadrature amplitude modulation demonstrate the feasibility of the proposed system and methods. In comparison, the proposed system has the characteristics of low power consumption, simple structure and reconfigurable digital modulation.
