# LTE MIMO - Multiple Input Multiple Output

Multi-antenna scheme - 2x2 MIMO:

MIMO techniques are multi-antenna techniques used in wireless devices to support higher data rates into radio links or RF. MIMO stands for Multiple Input Multiple Output antenna system. A set of mathematical equations are used to determine performance improvements. We will be discussing the 2x2 MIMO antenna architecture below.

MIMO is discussed below for 2x2 antennas: Before we discuss the mathematical equations for MIMO, lets first discuss the theoretical setup of a 2X2 MIMO.
