| 摘 要： | 多输入多输出(MIMO)技术是LTE系统中的关键技术之一,能够在不增加带宽的情况下成倍地提高了通信系统的容量和频谱利用率。本文提出了一种多用户MIMO下行链路中基于卡尔曼滤波的信道预测算法。在实际传输时,发射端根据接收端反馈回来的信道信息预测出下一时刻的下行信道信息,仿真结果验证了所提方法的有效性。

| Abstract: | Multiple Input Multiple Output(MIMO) technology is the key technology of LTE system.It can exponentially increase the capacity and spectrum efficiency of communication system in the case of not increasing the bandwidth.This paper proposes a channel prediction algorithm in multi-user MIMO downlink based on Kalman filter.In actual transmission,the transmitter predicts downlink channel information of next time according to the back channel information.The simulation results verify the effectiveness of the prop... |
