MN-DMD2050E Revision 2 3–37
Carrier-in-Carrier link design involved trying different Modulation & FEC Code Rates to find the
optimal combination:
• 8-QAM, LDPC 2/3 with Carrier-in-Carrier
• QPSK, LDPC 3/4 with Carrier-in-Carrier
• QPSK, LDPC 2/3 with Carrier-in-Carrier
• QPSK, LDPC 1/2 with Carrier-in-Carrier
