Please try to understand the question and then reply.

Please check only yellow highlighted terms on page number 2068. Eq. 70 is converted into eq. 71 using formula ||vec(A)||_2^2 = tr{AA^H} (3rd line of appendix). My question is In eq 70, the term H*V*V^H*H^H is inside, and R is outside the diagonal operator as tr{R*...

How to derive (proof) the following trace(A*Diag(B*B^T)*A^T) = norm(W,2), where W = vec(sqrt(diag(A^T*A))*B) & sqrt(diag(A^T*A)) is the square root of diag(A^T*A), B & A are matrix. Please see the equation 70 and 71 on page 2068 of the supporting matrial.
