Abstract—Minimizing the sum of mean squared errors using linear transceivers under a sum power constraint in the multiuser downlink is a non-convex problem.
Abstract—In the multiuser downlink, power allocation for linear precoders that minimize the sum of mean squared errors under a sum power constraint is a ...
