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.
