DESCRIPTION
"
Selects Inner FEC code rate type.
Changing the encoder will affect symbol rate and data rate.
Valid values include:
QPSK - viterbi1_2(1), viterbi2_3(2), viterbi3_4(3), viterbi5_6(5), viterbi7_8(7)
8PSK - viterbi2_3(2), viterbi5_6(5), viterbi8_9(8)
16QAM - viterbi3_4(3), viterbi7_8(7)
Unsupported choices include:
none(0), viterbi4_5(4),viterbi6_7(6), viterbi9_10(9),viterbi10_11(10),viterbi11_12(11)
viterbi1_4(15), viterbi1_3(16), viterbi2_5(17)
