Hybrid rectifier-receiver node

Simultaneous Wireless Information and Power Transfer (SWIPT) studies the transmission of wireless energy and data in a single RF signal. It becomes interesting when a single receiver chain is able to both convert the RF power to DC power, while at the same time converting the RF signal to BaseBand (BB). A practical method to receive the RF signal and convert the signal to BB while simultaneously harvesting power is proposed. This purpose is possible by utilizing a two-tone signal with a suitable Hybrid Rectifier-Receiver (HRR). The efficiency of the rectifier with different symbols can vary from 39% to 43% considering the power of the first tone as -11 dBm. Therefore, all symbols provide a descent DC output power. The proposed decoding is able to grasp the non-linearity of the diode in order to have a precise estimation of the symbols with different power levels.
