- Abstract
- This paper presents a wireless power and synchronized fullduplex data transceiver (WPSFDT) system using a single inductive link. This system employs TRX synchronization (TRXS) for synchronized data recovery (SynDR) of both offduration shift keying (ODSK) downlink and short-pulse load shift keying (SP-LSK) uplink. The envelope hold scheme ensures robust full-duplex (FD) data telemetry by mitigating self-interference (SI) caused by uplink data transmission. Measured results demonstrate that the proposed system achieves, for the first time, 400 kbps synchronized FD data transmission using a single inductive link through TRXS without any additional components for frequency separation.
