Hi Senghour Mey,

I understand that you are facing issue regarding how to express the above equation in the form of MATLAB code.

I assume that the variables specified in the equation above are already created in workspace with all the dimensionality constraints satisfied. Let these variables be denoted in MATLAB as follows:-

• h : h_r_H
• Θ : theta
• G : G
• h : h_d_H
• w: w
• s: s
• n: n
• σ: sigma

Now, this can be solved as follows: -

y = (h_r_H*theta*G + h_d_H) *w*s + n  

where the variable n (white gaussian noise with variance σ) can be generated as follows:-

n = normrnd(0,sigma)  

For further information regarding the function normrnd(), refer to the documentation: https://www.mathworks.com/help/stats/normrnd.html

I hope this answers your query.
