Energy Efficient Power Allocation for Multicell Distributed Antenna Systems

In this letter, we address the problem of energy efficient coordinated power allocation in a multicell distributed antenna system (DAS). Due to the mutual coupling of multiple cells caused by intercell interference (ICI), the problem is nonconvex and, therefore, is difficult to solve. We assume that...
