I have recently been learning how to use CVX to solve some simulation problems in communications, and I now have some difficulties in trying to write out this objective function. I would appreciate your help.

Here is the simulation problem and the symbol \Re indicates the real part of a complex number.

Where \mathbf{V} is the variable I need to optimise, its subscript k represents the number of users and the matrices \mathbf{A} and \mathbf{B}_k are both known matrices.

I would be very grateful if I could get an answer from you.
