English abstract:
We introduce an iterative solution to the problem
of interference alignment (IA) over MIMO channels based on a
message-passing formulation. We propose a parameterization of
the messages that enables the computation of IA precoders by a
min-sum algorithm over continuous variable spaces - under this
parameterization, suitable approximations of the messages can
be computed in closed-form. We show that the iterative leakage
minimization algorithm of Gomadam et al. is a special case of our
message-passing algorithm, obtained for a particular schedule.
Finally, we show that the proposed algorithm compares favorably
to iterative leakage minimization in terms of convergence speed,
and discuss a distributed implementation.
