Buffer-Stable Adaptive Per-Module Power Allocation for Energy-Efficient Millimeter-Wave Modular Antenna Array (MAA) Platforms

Abstract

This paper proposes an adaptive algorithm that controls power allocation for each antenna module in millimeterwave (mmWave) modular antenna array (MAA) systems. In the system, multiple MAA modules exist; and the proposed algorithm dynamically allocates powers to MAA modules depending on the buffer in terms of the joint optimization of energy-efficiency and buffer stability, in each unit time. Performance evaluation results show that the proposed algorithm (i) avoids buffer divergence; and (ii) presents energy efficiency improvements.
