DMD2050E Universal Satellite Modem
In a number of ways, CnC carriers behave similar to conventional carriers in satellite links. They
are both exposed to adjacent carriers, cross-polarization and rain fade, and exhibit impairments
when any of these become too great. In addition, CnC operates in an environment where:
Carriers intentionally occupy the same spectral slot;
•
Performance depends upon desired and co-located interfering carrier.
•

Operational Guidelines

The rules for CnC operation are summarized below:
Both earth stations share the same footprint so each sees both carriers;
•
CnC carriers are operated in pairs;
•
One outbound with multiple return carriers is not allowed;
•
Asymmetric data rates are allowed;
•
