Abstract
A system is configured to measure (602) a forward error correction (FEC) decoding property (216) associated with applying FEC decoding (214) to FEC-encoded bits or symbols at a receiver device (202) deployed in a communication network (100). The system is configured to provide (606) an assessment of operating conditions of the receiver device based on the FEC decoding property. The FEC decoding property comprises, for example, a distribution of a number of iterations of a FEC decoding operation applied to a plurality of FEC blocks processed within a period of time. In some examples, the FEC decoding property comprises any one of heat, temperature, current, voltage, active clock cycles, idle clock cycles, activity of parallel engines, activity of pipeline stages, and input or output buffer fill level of the FEC decoding. The assessment is based, for example, on a comparison between the FEC decoding property and reference FEC data (218).
