Adds pilots to T2 frames.
This is the template for the [[:Category:Block_Docs|"Page-per-block Docs"]].  This first section should describe what the block does and how to use it, using however many paragraphs necessary.  Note that the title of the wiki page should match the block's name in GRC, i.e. the one defined in the block's .grc file.  Look at the [[FFT]] Block for a good example.


As this is a basic template, it's also in the [[:Category:Stub_Docs|"Stub Docs category"]]. Please improve it.

Adds pilots to T2 frames.

Input
Frequency interleaved T2 frame.
Output
T2 frame with pilots (in time domain).

Parameters

Extended Carrier Mode
Number of carriers
FFT size
OFDM IFFT size
Pilot pattern
DVB-T2 pilot pattern
Guard interval
OFDM ISI guard interval
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
MISO Group (if Preamble to MISO)
MISO transmitter ID
Sin(x)/x equalization
sin(x)/x DAC equalization
Bandwidth (if above to on)
sin(x)/x equalization bandwidth

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.
