Abstract
In the above paper, Behbahani et al. proposed a closed-form solution (in Section III-B-1) for the optimal relay coefficients by minimizing the minimum mean-square error (MMSE) at the destination subject to a global power constraint at the relays. We provide corrections to this closed-form solution and a few comments.
