Description: This attribute represents the peak-to-peak group delay ripple expressed in units of 0.001 nsec. This attribute represents the group delay variation across the entire OFDM channel. The slope component calculated for the GroupDelaySlope is subtracted from the frequency domain data and the peak-to-peak ripple is calculated from the resultant data.
What is docsPnmCmOfdmChEstCoefGrpDelayRipplePkToPk?
The peak-to-peak group delay ripple, in thousandths of a nanosecond, across the whole downstream OFDM channel, after subtracting the linear group-delay slope. High group-delay ripple points to reflections or filter response issues in the plant that can distort symbol timing.
