COFDM Video Receiver Anti-electromagnetic interference performance:
It has superior performance against frequency selective fading or
narrow bandwidth interference and signal waveform interference. It
has strong anti-fading ability, through each subcarrier joint
coding. In single carrier system(digital microwave, spread spectrum
system, etc), single decline or interference will result in all
communication link failure. But in multiple carrier COFDM system,
only a few subcarriers will be interfered What’s more, these
sub-channel can adopt ECC to correct error, to guarantee the
transmission low error rate.
COFDM Video Receiver Anti-multipath fading:
It can confront signal waveform interference effectively; suitable
for multi-path environment and fading channel high-speed data
transmission. When the frequency selective fading appear in the
channel because of multi-path transmission, only the sub-carrier,
which fell over the band depression, and the information carried
will be affected. Other sub-carriers will not be affected. Thus,
the system total error rate performance will be much better.
