My name is Yuri.
I very new to GNU Radio, and I’m using GRC 3.7.1.
I am doing a research, and I need to modulate specific signal in OFDM. I
would like to insert cyclic prefix (or guard interval in my project, the
same thing with a different name).
I looked at the examples
/examples/ofdm, and I’ve also read some papers about OFDM technics.
My doubt is: what is the parameter “Length Tag Key”? I’ve seen it
in the examples located in the folder above, I’ve tried to do the same
my project, but it states a message that this parameter is missing.
By chance, does this cyclic prefixer block only works with other blocks
the same category? I mean, do I need to use OFDM carrier allocator
it, or something like that?
Thank you for your attention,
