USER'S MANUAL. MO-160
Hierarchy: Using this function the COFDM modulator is switched between
hierarchical mode, with different alpha constellation ratios, and non-
hierarchical mode operation. The options available are:
OFF:
non-hierarchical operation.
a=1:
hierarchical mode with alpha = 1.
a=2:
hierarchical mode with alpha = 2.
a=4:
hierarchical mode with alpha = 4.
HP Code Rate: Using this function, the user can modify the convolutional
code rate for the High Priority (HP) Transport Stream (TS). The available
options are as follows:
1/2
2/3
3/4
5/6
7/8
LP Code Rate: Using this function, the user can modify the convolutional
code rate for the Low Priority (LP) Transport Stream (TS). The available
options are as follows:
1/2
2/3
3/4
5/6
7/8
Constellation: Here the menu allows the selection of one of the available
constellations. The options are:
QPSK
16QAM
64QAM
Guard Interval: This function selects the required guard interval for the
COFDM signal. The available values are:
1/4
1/8
1/16
1/32
