Maps T2 frames.

Input
Cell and time interleaved QPSK, 16QAM, 64QAM or 256QAM modulated cells.
Output
T2 frame.

Parameters[edit]

FECFRAME size
FEC frame size (normal or short).
Code rate
FEC code rate.
Constellation
DVB-T2 constellation.
Constellation rotation
DVB-T2 constellation rotation (on or off).
FEC blocks per frame
number of FEC frames in a T2 frame.
TI blocks per frame
number of time interleaving blocks in a T2 frame.
Extended Carrier Mode
number of carriers (normal or extended).
FFT Size
OFDM IFFT size.
Guard Interval
OFDM ISI guard interval.
L1 Constellation
L1 constellation.
Pilot Pattern
DVB-T2 pilot pattern (PP1 - PP8).
T2 Frames per Super-frame
number of T2 frames in a super-frame.
Number of Data Symbols
number of OFDM symbols in a T2 frame.
PAPR Mode
PAPR reduction mode.
Specification Version
DVB-T2 specification version.
Preamble
P1 symbol preamble format.
Baseband Framing Mode
Baseband Header mode.
Reserved Bits Bias Balancing
set all L1 bias bits to 1 (on or off).
L1-post Scrambling
scramble L1 post signalling (on or off).
In-band Signalling
In-band type B signalling (on or off).

Example Flowgraph[edit]

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
