Description
Summary:In this paper, a novel and efficient improved spectrum allocation scheme of DFT-SOFDM in a frequency selective channel is presented. The proposed scheme exploits data conjugate mapping on the basis of inter-carrier interference (ICI) cancellation, which has low complexity but high performance. The illustrative examples over Least Square (LS) and Linear Minimum Mean-Squared Error (LMMSE) equalization demonstrate that the proposed scheme can achieve better BER and Peak to Average Power Ratio (PAPR) performance compared to the conventional distributed spectrum allocation scheme in DFT-SOFDM system.
