Hello, is there anyone know about state space theory?

I wish to know how a random digital signal and the channel coefficient can be transform into state space domain in Matlab.

Please teach me about this subject or give me some website or notes about the question.

Thank you.
 

You can use the MATLAB command 'ss'. give the transfer function as input and get state variables out. for example a four state system is converted as below:

[A, B, C, D] = tf2ss(num, den);

more info here, look at the end of the page.
