Chapter 4 - Operation and Administration
The default is the highest supported Modulation Level.
SNR > 23 dB
21 dB < SNR < 23 dB
16 dB < SNR < 21 dB
13 dB < SNR < 16 dB
10 dB < SNR < 13 dB
8 dB < SNR < 10 dB
7 dB < SNR < 8 dB
6 dB < SNR < 7 dB
* The maximum supported value depends on the unit's HW revision and on the Max Modulation
Level according to the Sub-Band.
4.2.6.5.6 Average SNR Memory Factor
The Average SNR Memory Factor defines the weight of history (value of last
calculated average SNR) in the formula used for calculating the current average
SNR for received data frames. This average SNR is used by the ATPC algorithm in
the AU and is also included in the Adaptive Modulation Algorithm information
messages transmitted by the AU and the SU. The higher the value of this
parameter, the higher is the weight of history in the formula.
Available values: -1 to 32. -1 is for no weight for history, meaning that average
SNR equals the last measured SNR.
Default value: 5
172
