I was doing the simulations for the multitap frequency domain
equalization for multicarrier system (DMT based). It seems though the
at the band edges (First few tones and last few tones) higher
performance can be achieved if we use higher number of equalizer taps.
Can you people please suggest me any reasons why that happens or at
least guide me to any publication that might help me understand the
behaviour of the tones at the band edge for multicarrier system.
