中文说明：应用背景 在LTE系统中，由于天线间的隔离度不够而存在的回波干扰问题，接受天线接受到来自信源与发射天线的信号，严重的影响到了信号的正确接受。 关键技术本资源首先在MATLAB平台下搭建起了LTE系统链路仿真系统，在信号的接受端，OFDM信号被解调输出，由导频信息获得信道状态，进而运用干扰消除算法消除干扰。
English Description：
Application backgroundIn the LTE system, because of the lack of isolation between antennas and the echo interference problem, the receiving antenna receives the signal from the source and transmitting antenna, which seriously affects the signal.Key TechnologyThis resource is built on the MATLAB platform, the LTE system is built up. In the signal receiving end, the OFDM signal is received by the channel state, and the interference cancellation algorithm is used to eliminate the interference.
