Output: OFDM T2 frame with P1 symbol.

== Parameters ==

; Extender carrier mode

; 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.
