MPR-e
- In the Reference Modulation field, select the suitable Modulation scheme.:
MPR-E: up to 256 QAM for MPT-HC V2, MPT-MC, and MPT-XP
MPR-A: up to 256 QAM for MPT-HC V2, MPT-XP, and 9558HC
- Based on the selected Channel Spacing and the Reference Modulation, the
relevant capacity will appear in the capacity field.
→ Operation with Adaptive Modulation (ACM)
Adaptive Modulation in a point-to-point system is to adjust the modulation as
well as a range of other system parameters based on the near-instantaneous
channel quality information perceived by the receiver, which is fed back to the
transmitter with the aid of a feedback channel.
The switching between the modulation schemes is hitless and maintains the same
RF channel bandwidth.
To configure Adaptive Modulation:
- In the Coding Modulation Type field, select "Adaptive (ACM)".
- In the Channel Spacing field, select the suitable channel spacing.
- Select the Modem Profile Option: Current Mask Standard Profile or New
Mask Standard Profile.
MPR-E: Current mask standard profile or New mask standard profile
MPR-A: Choose Standard Profile
- In the Reference Modulation field, select the reference modulation, which
corresponds to the lowest modulation scheme.
- In the Allowed Modulation field, select all the modulation schemes to be
used with the Adaptive Modulation. The modulation schemes (from the
lowest to the highest scheme) must be contiguous.
Warning: If the changes increase the current radio bandwidth, the warning message
(Figure 105) will be raised to the operator. The new setting must be validated with Alcatel-
Lucent.
