Abstract
Devices and methods for communicating back-channel data over a communication link are provided. The termination impedance of the communication link at the receiver and/or 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.
