A minimum distance analysis of a certain class of two dimensional ISI channels

In English In this paper we perform a minimum distance
analysis of a class of two dimensional intersymbol interference
channels. In particular, some important cases of multitrack
multihead magnetic recording systems fall into the studied class.
Previously, Soljanin and Georghiades have studied the same problem
as we do. The results derived in this paper are more conclusive
and they improve upon theirs. The fundamental proof technique that
we will use is to transform the channel into an equivalent minimum
phase channel.
