This paper proposed a method to generate precoding
which is applicable to the TD-LTE system.This method contains three parts:channel state information (CSI) model
energy distribute model
and beam-forming model.This scheme fully uses the character of exchanging channel for the TDD system
which can obtain the CSI of the downlink channel
and enhances the performance of anti-interference by using the precoding 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 precoding method is designed for Rice channel with LOS.This method can keep the precoding algorithm based on non-codebook at a quick convergence speed with low calculation complexity.
