CDM-700 High Speed Satellite Modem Revision 5
Introduction MN/CDM700.IOM
1.2.2 Turbo Product Coding (TPC)
The modem has Turbo Product Coding (TPC) available. TPC simultaneously offers increased
coding gain and lowers decoding delay. The TPC rates are:
Rate 3/4 QPSK, 8-PSK, 16-QAM, 64-QAM
Rate 7/8 QPSK, 8-PSK, 16-QAM, 64-QAM
