Writing equations representing a block diagram

[Communications_Engineer]

Hello, please help me learn the way to write equations for a block diagram, that I have for a communication system.

The block diagram is shown in figure.

I believe the model is quite simple but I am willing to explain the model, if it is required.


Actually, I do not know how to represent the process of "symbol repetition onto parallel streams", or "serial to parallel conversion" or "parallel to serial conversion" (used here for time combining).


I have some idea about other steps but it would be nice to learn the optimal manner to write it.



Thanks.

Have you tried using N 1:N deciminators for serial to parallel conversion?

I found this tutorial but I don't know whether it helps. I've never tried to write equations for block diagrams, but I think it is quite useful to do so, If I found more relevant resources I'll post it here.
