Graphics, Figures & Tables ⇒ Diagram figure in LaTeX with TikZ

[kostao]

Hello,
I am writing my dissertation using latex. Can you help me to create this figue in LaTeX (see below)?

The similar scheme http://www.texample.net/tikz/examples/radix2fft/ (Tikz example).
Thanks.

It looks like an algebraic diagram. You could use tikz-cd or a TikZ matrix, such as here - putting the symbols into a matrix, and drawing some arrows. Perhaps I post an example later today. Btw. I added an answer to your other question with tcolorbox.

A simple example of a commutative diagram using TikZ, short and readable.
It has been posted as answer to the question
http://tex.stackexchange.com/q/45741/213 of Elias.
* A matrix is used for positioning the main nodes
* Arrows are drawn as edges, between the main nodes,
  using further nodes for labeling
* As columns and row distance is expressed by em units, which scale
  with the font size, the diagram can be scaled by using font size commands
  such as \Large, \huge etc.
Note the (m-2-1.east|-m-2-2) syntax for getting a horizontal arrow
between cells of a different height.
