Matched filter and LMS equalizer - Richard_K - 2006-12-27 16:56:00

Hi,

Is it possible for a LMS equalizer in multipath environment to achieve
better BER performance as compared to matched filter in AWGN channel?

Only if the total multipath energy is higher then that in the AWGN case.

If by "AWGN channel' the OP meant "channel without multipath," 
I disagree. The equalizer *might* perform _as well_ as the
matched filter, but not better.
