Abstract
A coded signal is received via a physical link and decoded. A link loss of the physical link is detected based on at least one of the coded signal and said decoding.
Claims20
A method, comprising:
- receiving a coded signal via a physical link,
- decoding the received coded signal to obtain a result signal,
- detecting a link loss of a disturber physical link based on the coded signal, the decoding of the coded signal, or both, wherein an error correction code is determined to combat noise related to the disturber physical link, wherein an action is to be taken responsive to the link loss of the disturber physical link that includes a mitigation of an effect related to the link loss of the disturber physical link, the link loss being further determined based on energy across a plurality of samples in a frequency domain.
A device, comprising:
- a receiver configured to receive a coded signal via a physical link, the coded signal having been coded by a Trellis coded modulation (TCM) encoder,
- a decoder configured to decode the received coded signal to obtain a result signal,
- at least one processor configured to detect a link loss of a disturber physical link based on the coded signal, the decoding of the coded signal, or both, wherein an error correction code is determined to combat noise related to the disturber physical link, wherein an action is to be taken responsive to the link loss of the disturber physical link that includes a mitigation of an effect related to the link loss of the disturber physical link, the link loss being further determined based on energy across a plurality of samples in a frequency domain.
