摘要：
This paper proposed a method generating precoding, which is suit to use in the TD-LTE system. This method contains three parts as following, channel state information (CSI) model, energy distribute model, and beam-forming model. This scheme fully use the character of exchanging channel for the TDD system, which can obtain the CSI of the downlink channel, and enhances the performance to defense the interference by using the pre-coding based on the non-codebook. Furthermore, it can enlarge the range of the serving cell. The background of this paper is LTE downlink system equipped with these spatial-correlated receive antennas, where a transmitted pre-coding method is designed for Rice channel with LOS. This method can keep the pre-coding algorithm based non-codebook quick convergence speed with low calculation complexity. © 2016, Chinese Institute of Electronics. All right reserved.
