MIMO transmission schemes for LTE and HSPA networks

Smart antenna, or multiple-input multiple-output (MIMO), technology is commonly defined as, the use of two or more unique radio signals, in the same radio channel, where each signal carries different digital information, or two or more radio signals that use beam forming, receive combining and spatial multiplexing (SM).

Relative to a traditional 1x1 antenna system, a 2x2 MIMO system is expected to deliver significant cell throughput gain. 

This report provides an overview and detailed information of the current and emerging MIMO techniques that significantly increase the performance of HSPA and LTE networks.
