Abstract:
Systems and techniques relating to channel degradation detection for communication systems are described. A described system includes a processor and an interface to transmit signals and receive signals via a channel that includes a cable. The processor can be configured to perform echo cancellation based on echo tap values to remove portions of the transmitted signals that appear as echoes within the received signals, signal equalization based on equalizer tap values, or both. The processor can be configured to determine a channel quality indicator of the channel based on one or more of the echo tap values, one or more of the equalizer tap values, or both. The processor can be configured to generate a warning indication based on the channel quality indicator indicating a degradation of the cable or the channel.

Claim (Index 16):
A system comprising:\n a first device of a car, the first device comprising an interface to transmit signals and receive signals via a channel that includes a cable that is subjected to an automotive environment of the car, and a processor coupled with the interface; and a second device of the car, the second device being communicatively coupled with the first device via the cable, wherein the processor is configured to perform i) echo cancellation based on echo tap values to remove portions of the transmitted signals that appear as echoes within the received signals, ii) signal equalization based on equalizer tap values, the equalizer tap values being determined based on at least a portion of the received signals to adjust an impulse response of the channel and reduce inter-symbol interference within the received signals, or iii) both the echo cancellation and the signal equalization, wherein the processor is configured to determine a channel quality indicator of the channel based on one or more of the echo tap values, one or more of the equalizer tap values, or both one or more of the echo tap values and one or more of the equalizer tap values, and wherein the processor is configured to detect a degradation of the cable or the channel over time resulting from being subjected to the automotive environment of the car based on the channel quality indicator.
