As shown schematically in Figure A-1, the initially estimated signal and noise are denoted by
and
, respectively. By projecting
to the direction of
, we can get the projection
. The other component of
is the final estimated noise, as shown in equation 3. The final estimated signal is thus the summation of the initially estimated signal
and the projection component
.
When
, the following equation holds:
