Modulation Scheme
NB/UMVL
DVB-T
This box enables you to select the modulation mode you want
to work with. Different schemes have different settings.
5.5.3 Narrowband Settings
If you selected NB/UMVL for the modulation scheme, these settings need to be configured.

Bandwidth
Narrowband:
2.5MHz
1.25MHz
625kHz
UMVL:
6MHz
7MHz
8MHz
DTC Narrowband modes provide excellent range and efficient use
of available channel bandwidth.
DTC Ultra Mobile Video Link modes provide higher data throughput
than Narrowband by using the same bandwidths as DVB-T. UMVL
will provide an advantage over DVB-T at C/X-band in short range
mobile environments.
Constellation
QPSK
16QAM
BPSK
8PSK
QPSK, BPSK and 8-PSK – less user data, more robust, more range.
16QAM – more user data, less robust, less range (link
performance reduced by 5db).
FEC Rate 1/3
2/3
The forward error correction (FEC) rate.
1/2 – 1 bit out of 2 bits is data and 1 bit is for error correction.
2/3 – 2 bits out of 3 bits are data and 1 bit is for error correction.
More user data means better picture quality, but less error
correction means less robust signal and thus less range.
