DTTB TransmitterNon - linear considerations
The non - linear performance is shown by the intermodulation character displayed in the transmitted spectrum.
The required intermodulation performance is influenced by the multipath performance of the consumer’s receivers.
The performance of a receiver is influenced by the modulation type eg :
- whether 64QAM, 16QAM or QPSK
- and whether FEC is 7/8, 5/6, 3/4, 2/3, or 1/2
