Application of lattice code decoder to SC-CP for short block length

Currently, the single-carrier cyclic prefix (SC-CP) uses a receiver based on a frequency-domain equaliser. It is proposed to use the lattice code decoder in SC-CP. Since the lattice code decoder is now available for near maximum-likelihood (ML) decoding, the proposed SC-CP detector outperforms the detector based on the equalising technique, especially for the channel with spectral nulls.
