Abstract: A cable modem transceiver includes a processor configured to derive an instant of time for an upstream calibration signal on basis of upstream scheduling information. Further, the cable modem transceiver includes a transmitter configured to generate the upstream calibration signal at the derived instant of time. The cable modem transceiver additionally includes a detector configured to determine a property of the generated upstream calibration signal. The processor is further configured to derive at least one calibration parameter for the transmitter on basis of the detected property.
