摘　　要：传统5G多载波通信中信道估计干扰抑制算法存在着均衡性能较差的问题,表现为误码元数与误码率偏高,因此文章提出5G多载波通信中信道估计干扰抑制均衡算法。该算法首先对干扰项进行过采样处理,引入预处理矩阵以减小模损失的影响,对信道估计干扰进行均衡抑制。仿真实验结果表明,在信噪比相同的情况下,5G多载波通信中信道估计干扰抑制均衡算法的误码元数比两种传统算法分别低了161、192,其误码率分别低了24%、31%,均衡性能较好。The traditional channel estimation interference suppression algorithm in 5G multi carrier communication has the problem of poor equalization performance,which is characterized by the high number of error elements and bit error rate. Therefore,this paper proposes a channel estimation interference suppression equalization algorithm in 5G multi carrier communication. Firstly,the interference term is oversampled,and the pre-processing matrix is introduced to reduce the influence of mode loss. The simulation results show that under the same signal-to-noise ratio,the BER of channel estimation interference suppression equalization algorithm in 5G multicarrier communication is 161 and 192 lower than that of the two traditional algorithms,and its BER is 24% and 31% lower than that of the two traditional algorithms,respectively.
