Fundamentals for Energy-Efficient Massive MIMO

摘要

Implementing any massive MIMO array involves managing transmitter power dissipation heat from each element. This power dissipation is strongly lower-bounded by the signal adopted by present communication standards, which forces an energy efficiency minimum. This also causes a difficult thermal problem in the array implementation. Achieving an energy efficient massive MIMO implementation is shown to require the use of strongly nonlinear transmitters, needing signal designs that are compatible with this nonlinearity while maintaining bandwidth efficiency.
