A technique for reducing data converters in MIMO systems

Abstract

We propose a technique to reduce the number of data converters in multiple-input multiple-output (MIMO) systems. While the conventional MIMO systems require the same number of data converters as that of antennas, the proposed method requires only one high speed data converter and one analog switch, regardless of the number of antennas. Hence, the power consumption and implementation area can be reduced. The experiment results confirm the effectiveness of the proposed technique.
