From some technical papers, I found out that non-adaptive MMSE block equalizer has been used to equalize for time-varying channels. Since adaptive algorithm (LMS, RLS,....) is not applied here, then how the researchers simulate for the BER performance? Can anyone please help? Thanks.

For non-adaptive LMMSE equalizer, will the performance (both convergence and MMSE) affected by the eigenvalue spread just like LMS algorithm? Besides, how can non-adaptive MMSE block equalizer being used to equalisze for time-varying channels?>From some technical papers, I found out that non-adaptive MMSE block >equalizer has been used to equalize for time-varying channels.
