Title: "Blind separation of constant modulus signals"

Abstract:
---------
In my talk I will describe the problem of recovering a linear
transformation from points in the image together with some a-priori
knowledge of the statistical properties of the sources. This problem is
known as blind source separation or independent component analysis (when
sources are independent random variables). The problem has many flavors
which I will review. Then I will concentrate on the case where the sources
are known to have constant modulus, and we are given finitely many points
in the image. More specifically I will provide bounds on the probability
of identifiability of the linear transformation given finite amount of
samples. If time permits I will also discuss other related problems.
