G.3.4.1 Symmetric Data Rate Link
Consider this example:
Satellite & Transponder
Earth Station 1
Earth Station 2
Data Rate
The traditional link was based on QPSK TPC 3/4 and required 0.96 MHz of leased BW. The LST
(Intelsat's Lease Transmission Plan Program) summary for the traditional link is as follows:
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
