Description: This attribute is the RxMER value corresponding to the specified Percentile value. The CM sorts the subcarriers in ascending order of RxMER, resulting in a post-sorting subcarrier index ranging from 1 to the number of active subcarriers. If the percentile value corresponds to a non-integer post-sorting subcarrier index, the post-sorting index is truncated (floor function is applied), that is, the post-sorting index is selected which is the greatest integer less than or equal to the corresponding percentile value. For example, if there are 3677 active subcarriers and the 2nd percentile is specified, the CM computes floor(3677*0.02) = 73. That is, the RxMER value of the 73rd subcarrier in the sorted list is associated with the 2nd percentile.
What is docsPnmCmDsOfdmRxMerThrVal?
The RxMER value, in quarter-dB steps, corresponding to the configured percentile after sorting all active subcarriers by MER ascending; e.g. with 3677 active subcarriers and a 2nd percentile, this is the 73rd-worst subcarrier's MER. Gives a single number representing 'how bad are the worst few percent of subcarriers', more actionable than a channel-wide mean.
