Abstract
Filterbank based multicarrier modulations are well known to
perform poorly in frequency selective channels when single
tap carrier-by-carrier equalization is used. This degradation is
cased by the inherent distortion in terms of inter-symbol and
inter-carrier interference at the receiving side, which cannot
be compensated via single-tap equalization. We provide here
an asymptotic characterization of this effect. More specifically,
we derive the asymptotic distortion after a single-tap
perfect equalizer under the assumption that the number of carriers
is asymptotically large.
