Channel Estimation Interference Suppression Equalization Algorithm for 5G Multicarrier Communication

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.
