Title:
DIFFERENTIAL TERMINATION MODULATION FOR BACK-CHANNEL COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2019/210793
Kind Code:
A1
Abstract:
Devices and methods for communicating back-channel data over a communication link are provided. The termination impedance of the communication link at either or both of the receiver and the transmitter side may be modulated to encode back-channel data as signal reflections in the communication link. The corresponding device at the other end of the communication link may detect these reflections and decode them to recover the back-channel data.
