This paper addresses energy efficiency (EE) optimization problems for uplink multiuser multiple-input-multiple-output (MIMO) systems with zero-forcing (ZF) transceivers, subject to a joint power and rate constraint for each user. As the optimization problem considered in this paper is quite differen...
