| 英文摘要: |
| An interference suppression design scheme based on conjugate weighted butterfly interleaving mapping ( CWBIM) is proposed for inter-carrier interference ( ICI) and inter-subband interference (IBI)in the received signals of universal filtered multi-carrier ( UFMC) systems. It applies an interleaving mapping operation to subtract the interference coefficients of adjacent terms in ICI and IBI twice , thereby achieving suppression effects similar to the self-cancellation ( SC) algorithm while maintaining the original data transmission efficiency. Meanwhile , conjugate and complex weighting operations can effectively suppress the impact of phase rotation errors in high-speed mobile channel environments , thereby further improving the bit error rate (BER)performance of the system , Moreover , butterfly operation can effectively control the computational complexity of the interleaving mapping process. Theoretical analysis and simulation results show that , compared with the PSC-UFMC algorithm , the CWBIM-UFMC scheme proposed in this paper can effectively suppress ICI and IBI in the received signal without compromising data transmission efficiency and reducing computational complexity , thereby achieving good BER performance of the system. |
