Blind channel estimation and MMSE equalization using Shalvi and Weinstein´s blind deconvolution criteria

This paper proposes a novel noise-insensitive approach to blind channel estimation using Shalvi and Weinstein´s (1994) blind deconvolution criteria. It is based on the relation between the associated equalizer and the nonblind minimum mean square error (MMSE) equalizer reported by Feng, Hsi and Chi (1999). As a by-product, the design of the MMSE equalizer is also presented without training phase. The proposed approach and the designed MMSE equalizer are then justified through computer simulation
