Figure 3-13. Conceptual Block Diagram
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.
3.11.3 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;
