MMSE equalization with weighted SNRs for DVB-T receivers

Abstract

When channels are slow fading, the MMSE equalizer can be considered for DVB-T receivers without matrix inversion. However, incorrectly-applied SNR values may degrade the equalization performance. To solve the problem, we propose a MMSE equalizer with weighted SNRs by the magnitudes of the estimated channel coefficients. ©2008 IEEE.
