  • Automatic OFDM profile selection
    Patent number: 11336499
    Abstract: Assigning an appropriate modulation profile for an orthogonal frequency-division multiplexing (OFDM) channel. The current modulation profile assigned to a specific OFDM modem for communicating over a specific OFDM channel is examined to determine whether to consider reassigning the specific OFDM modem to a different modulation profile. Only upon determining consideration should be given, an assessment is made as to which modulation profile, of a set of candidate modulation profiles available to that OFDM modem for communicating over the specific OFDM channel, should be assigned to the specific OFDM modem using linear domain averaging over the OFDM subcarriers of the ratios between a Mean Error Rate (MER) threshold per subcarrier for the specific OFDM modem and the MER reported by the specific OFDM modem per subcarrier. A new modulation profile is assigned to the specific modem based on the assessment.

  • Automatic OFDM Profile Selection
    Publication number: 20210091989
    Abstract: Assigning an appropriate modulation profile for an orthogonal frequency-division multiplexing (OFDM) channel. The current modulation profile assigned to a specific cable modem for communicating over a specific OFDM channel is examined to determine whether to consider reassigning the specific cable modem to a different modulation profile. Only upon determining consideration should be given, an assessment is made as to which modulation profile, of a set of candidate modulation profiles available to that cable modem for communicating over the specific OFDM channel, should be assigned to the specific cable modem using linear domain averaging over the OFDM subcarriers of the ratios between a Mean Error Rate (MER) threshold per subcarrier for the specific cable modem and the MER reported by the specific cable modem per subcarrier. A new modulation profile is assigned to the specific modem based on the assessment.
