Abstract:

In order to reduce the symbol error rate of the conventional single-carrier frequency-domain equalization(SC-FDE) system with cyclic prefix(CP),a structure of SC-FDE with three-dimension signal mapping is proposed,which substitutes 3D signal mapping for the traditional 2D one and converts 3D signals to 2D ones.As only the symbol mapping is changed,the conventional SC-FDE with CP can be easily substituted.Simulated results show that,as compared with the conventional SC-FDE with 2D signal mapping,the proposed structure is of significantly improved error performance and is suitable for the transmission system with low power.

Key words: single-carrier frequency-domain equalization, three-dimension signal mapping, minimum Euclidean distance, multipath fading
