### Diagram figure in LaTeX with TikZ

Hello,
I am writing my dissertation using latex. Can you help me to create this figue in LaTeX (see below)? diagram.png (142.49 KiB) Viewed 2032 times

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.
