Novel Efficient Precoding Technique with Reduced Feedback for Multiuser MIMO Systems with Multiple Antenna User Equipment

Abstract

Capacity and noise immunity of wireless systems with multiple antenna technology can be increased by using new precoding techniques. The main goal of this article is to present new efficient nonlinear ordered precoding technique with reduced feedback channel for wireless systems with multiple antenna base station (BS) and user equipment (UE).Proposed precoding technique provides to increase average capacity of user channel and decrease required capacity of feedback channel.
