We consider frequency-domain equalization of single-carrier systems in doubly-selective channels. In this framework, we investigate the role of channel extension in the time domain on the performance of extended frequency-domain equalization. Specifically, we propose a new low-complexity channel extension technique, whose comparison with other techniques is performed by evaluating the approximation error of the channel matrix and the BER of banded linear MMSE equalizers.

Abstract
We consider frequency-domain equalization of single-carrier systems in doubly-selective channels. In this framework, we investigate the role of channel extension in the time domain on the performance of extended frequency-domain equalization. Specifically, we propose a new low-complexity channel extension technique, whose comparison with other techniques is performed by evaluating the approximation error of the channel matrix and the BER of banded linear MMSE equalizers.File in questo prodotto:
