This dissertation begins with the analysis of the interference problems in heterogeneous networks, and demonstrates the necessity of interference cancellation at the terminal side against the background of heterogeneous network interference cancellation. Based on the theoretical analysis of the interference problem in LTE cell, this dissertation proposes the interference research idea of CRS interference elimination algorithm based on interference reconstruction and PBCH interference elimination algorithm to eliminate the influence of interference on link performance and improve the service quality of network Follow-up in the realization of the terminal has some guiding value.
