Advantages
of
COFDM
COFDM
modulation
has
very
strong
attenuation
resistance,
COFDM
modulation
enables
the
transmission
from
the
end
user
to
a
plurality
of
subcarriers,
and
the
signal
can
be
kept
very
much
longer
than
the
signal
kept
in
a
single-carrier
system
correspondingly,
so
COFDM
has
a
stronger
resistance
for
impulse
noise
and
fast
channel
attenuation
resistance.
COFDM
has
higher
utilization
of
frequency
and
allows
overlapping
orthogonal
subcarriers
waves
as
sub-channels,
rather
than
the
traditional
use
of
guard
bands
separating
the
sub-channels,
so
it
improves
the
frequency
efficiency,
and
maximizes
the
use
of
spectrum
resources.
As for high-speed data transmission, COFDM has its self-adaptive modulation mechanism which enables subcarriers to choose different modulation methods like QPSK, QAM, 16QAM or 64QAM according to different channel conditions and background noises. If the conditions are good, then adapt itself to the high-efficiency modulation, if the conditions are bad, then adapt to the anti-interference modulation. So it can reliably adapt to a high-speed data transmission.
It has strong Inter-Symbol Interference (ISI) ability, ISI is the major interference besides noise in digital communications. COFDM by using the cyclic prefix has the strong ability of ISI.
Ease of use in combination with a variety of other methods, COFDM can be used as a modulation method, besides, it can be easily combined with many kinds of multiple access technology, providing access for multiple users at the same time. You can allow multiple users to simultaneously use the COFDM information technology for transmission.

solved
the
difficult
problems
of
"Non-Line-of-Sight"
and
"Mobile"
wireless
broadband
transmission
when
rate
is
over
2Mbps,
so
it
has
been
widely
applied
in
mobile
communications,
video
transmission
and
monitoring
systems
such
as

(military,

and
other

The
system
can
collect
real-time

etc.
via
a
public

or
private

network
system
delivered
to
each

Officers
at
all
levels
of
command
can
understand
the
situation
from
the
computer
directly
to
take
effective
measures
in
real-time
command.
So
it
is
widely
applied
to
natural
disasters
emergency
services.
The
system
can
help
to
save
a
lot
of
processing
time
and
reduce
the
losses
caused
by
