SCA method. How to solve the problem with Matlab CVX?

How to solve the problem with Matlab CVX?

I lack experience in programming MATLAB CVX. Please give some advice.

I don’t even understand what all the notation and “behind the scenes” relationships are. Do you? Why don’t you start by carefully understanding exactly what everything in this optimization problem is and means? You should not expect forum readers to do that for you on an image you took from a paper or book.

SCA is in the title of this topic, so presumably the paper or book said something about using SCA. You need to figure out how SCA is used, and what the corresponding convex optimization (sub)problems spawned in the SCA are. Then you figure out how to code those in CVX.

And after all that, SCA itself can be very unreliable and non-robust.
