A novel and effective precoding scheme used in low speed movement scenario for 3GPP LTE-advanced system

Recently, the standardization of LTE-Advanced is in rapid process and more and more people concentrate on the system performance of special transmission scenarios and make improvement in current architectures because studies on both system throughput and capacity in physical layer are nearly saturated. The standardization of 3GPP LTE-Advanced release 11 has been opened in the early 2011 and Distributed Antenna System (DAS) is introduced to improve spectrum efficiency and system throughput. In this work, we proposed a novel method used in low speed scenario such as indoor and campus. Compared with current 3GPP specifications and proposals, our new method can effectively reduce the demand of channel estimations and will receive better or nearly the same performance. A system level simulation is also done to prove our method based on our Matlab-based system level simulation.
