Abstract

This paper demonstrates the effectiveness of an adaptive impedance control for mobile terminals with MIMO antennas, which aims to improve the antenna performance in the usage environment, over an FDD-LTE (Frequency Division Duplex - Long Term Evolution) system through experimental measurement by using a developed prototype terminal. Measurement results verify the effectiveness of a proposed control algorithm, which can not only achieve downlink MIMO throughput improvement, but also uplink transmission power reduction simultaneously.
