CVX objective function "maximize log2(1+rm)"

I tried the solver “SeDuMi” and CVX output just like figure.1.


When I chose Mosek as the solver, the result is shown in picture 2 and 3.
I found the two solvers got different results.

Then, the link about “CVXQUAD” I’ve ever considered before, but I didn’t try it.

For the output, since it is different from the paper I’m simulating, so I think the results is not right.
