[Show abstract][Hide abstract] ABSTRACT: Blind signal separation is currently an active research topic, and many techniques for accomplishing it have been discussed
in the literature. In his excellent survey article , Cardoso describes blind signal separation (BSS) as the recovery of
“unobserved signals of ‘sources’ from several observed mixtures”. This paper describes a particular implementation, a recently
constructed two-channel processor capable of operating on convolutive mixtures of QAM signals running at symbol rates as fast
as 40 MHz. This processor has been applied to several practical problems, including the cancellation of cross-pole interference
from a digital radio signal of interest and the diversity combination of signals received from two apertures or antenna feeds.
