Abstract

        As a theoretical concept, and a means to understand
the potential of interference alignment, in this paper we
investigate possibilities to place n transmitter-receiver pairs in
n - 1 dimensions such that the interference from unintended
transmissions is aligned at each receiving node. By such an
arrangement each link has half of the capacity available, at
least in theory. Regular patterns of stations are considered. It is
shown that placing transmitters “outside” a regular arrangement
of receivers provides solutions in any dimension, while placing
transmitters “opposite” to intended receivers only yields a solution
in dimension one and two. Methodologically we borrow
from the field of distance geometry.
