N2 - Combating the intersymbol interference is an important issue in single-carrier block transmission systems. To exploit the advantages of frequency-domain (FD) processing, we propose in this paper a hybrid-domain sequence detector that combines FD prefiltering with time-domain tree search detection. The proposed algorithm achieves a detection performance that is very close to that of the conventional tree search equalizers (which employ the QRD-M or sphere decoding algorithm), but with a much lower complexity. In addition, the proposed algorithm performs significantly better than the decision-feedback equalizer, with only a modest increase in complexity.
