TD-LTE下行传输采用了MIMO-OFDM的物理层构架，通过最多4个发射天线并行传输多个（最多4个）数据流，能够有效地提高峰值传输速率。LTE的物理层处理过程中，预编码是其核心功能模块，物理下行共享信道的几种主要传输模式都是通过预编码实现的。(The td-scdma LTE downlink transmission adopted MIMO - OFDM frame, the physical transmission antennas parallel transmission by up to four more (up to 4) data flow, can effectively improve the peak transmission rate.LTE) in the process of the physical layer of precoding is its core function module, several kinds of main physical downlink Shared channel transmission model is achieved by precoding.)

说明：  In this paper, a new direction-of-arrival (DOA) estimation method based on multiple Toeplitz matrices reconstruction is proposed for coherent narrow band signals with a uniform linear array (ULA).(Even in the case of a low signal-to-noise ratio and low snapshot number with half the array aperture reduced, the new method provides good performance on estimation and resolution.)

Effective methods of performing diversity selection in wireless systems has been demonstrated to significantly reduce bit error rate.
