Frame Mapper

Maps T2 frames.

Input

Cell and time interleaved QPSK, 16QAM, 64QAM or 256QAM modulated cells.

Output

T2 frame.

Parameters

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

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.
