Equalizer
Graph
Equalizer
graph
window
shows
adaptive
equalizer
taps’
coefficients,
which
at
a
set
time
moment
minimize
multipath
fading
effect
in
channel.
Example
of
equalizer
taps’
coefficients
and
its
frequency
response
in
case
of
a
normal
operation
is
shown
below:
Figure

Equalizer

with
flat
frequency
response
curve
During
normal
operation
frequency
response
curve
is
smooth
and
the
only
equalizer
tap
towers
are
in
the
centre
of
equalizer
taps
graph,
otherwise
frequency
response
curve
will
appear
jagged
and
many
equalizer
taps
will
become
visible.
The
latter
case
most
probably
will
indicate
to
multipath
issue,
which
must
be
inspected
with
use
of
precise
and
accurate
path
profiling.
An
example
of
multipath
caused
equalization
is
shown
on
the
picture
below.
Taps
mainly
on
the
right
side
designate
a
weaker
reflected
signal
in
comparison
with
the
main
signal.
