摘要

Load shift keying (LSK) has been widely used in a wireless power and data transfer (WPDT) system, owing to its low cost and power consumption. It was discovered that the demodulated data can flip when the coupling coefficient ( $k$ ) between the transmitter (TX) and receiver (RX) coils becomes less than a critical value (更多
