Simultaneous wireless information and power transfer transmitting architecture based on asynchronous space-time-coding digital metasurface

Simultaneous wireless information and power transfer(SWIPT) architecture is commonly applied in wireless sensors or Internet of Things(IoT) devices, providing both wireless power sources and communication channels. However, the traditional SWIPT transmitter usually suffers from cross-talk distortion caused by the high peak-to-average power ratio of the input signal and the reduction of power amplifier efficiency. This paper proposes a SWIPT transmitting architecture based on an asynchronous spac...
