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.
