Saturation Power-Based Simple Energy Efficiency Maximization Schemes for MISO Broadcast Channel Systems.

In this paper, we investigate an energy efficiency (EE) maximization problem in multiple input single output broadcast channels. The optimization problem in this system model is difficult to solve in general, since it is in non-convex fractional form. Hence, conventional algorithms have addressed the problem in an iterative manner for each channel realization, which leads to high computational com...
