Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The development of 5G enabling technologies brings new challenges to the design of por amplifiers (PAs). In particular, there is a strong demand for low-cost, nonlinear PAs which, hover, introduce nonlinear distortions. On the other hand, contemporary expensive PAs show great por efficiency in their nonlinear region. Inspired by this trade-off beten nonlinearity distortions and efficiency, finding an optimal operating point is highly desirable. Hence, it is first necessary to fully understand how and how much the performance of multiple-input multiple-output (MIMO) systems deteriorates with PA nonlinearities. ,  first reduce the ergodic achievable rate (EAR) optimization from a por allocation to a por control problem with only one optimization variable, i.e. total input por. Then,  develop a closed-form expression for the EAR, where this variable is fixed. Since this expression is complicated for further analysis, two simple lor bounds and one upper bound are proposed. These bounds enable us to find the best input por and approach the channel capacity. Finally, our simulation results evaluate the EAR of MIMO channels in the presence of nonlinearities. An important observation is that the MIMO performance can be significantly degraded if  utilize the whole por budget.
