In this paper, we propose a method to mitigate the interferences for single carrier frequency domain equalizer (SC-FDE) without cyclic prefix (CP). SC-FDE systems suffer from the interferences when CP is appended insufficiently. Inter block interference (IBI) is introduced by the previous block, and inter symbols interference (ISI) is also generated by imperfection of the circulant channel matrix...
This paper proposes a new residual carrier frequency offset (CFO) estimation technique for the unique word (UW) based single-carrier transmission with frequency domain equalizer (SC-FDE) on frequency selective channels. In extremely frequency selective channels, UW symbols for CFO estimation can also be corrupted by the inter-symbol interference (ISI). Since the UW can be included in the equalizer,...
