h(t)
x(t)
y(t)
Considering a “black box”, an input x(t) (transmitted),
the output y(t) (received), we want estimate the Impulse
Response h(t):
Choosing a couple of signals x(t)
and x(t)-1 (x(t) reversed on the time axis), that satisfy the relation:
and applying the
commutative property of the product is possible obtain the IR, h(t).
