Inserts a P1 symbol.
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.
Input: OFDM T2 frame.
Output: OFDM T2 frame with P1 symbol.

Inserts a P1 symbol.

Input: OFDM T2 frame. Output: OFDM T2 frame with P1 symbol.

Parameters

Extender carrier mode
Number of carriers
FFT size
OFDM IFFT size
Guard interval
OFDM ISI guard interval
Number of data symbols
Number of OFDM symbols in a T2 frame.
Specification version
Changes available preamble types
Preamble
P1 symbol preamble format.
Show peak IQ levels
print peak IQ levels.
Vclip
Set peak IQ level threshold.

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.
