Application Scenarios
Advantages of COFDM
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.
Applications of COFDM Device
High-speed Real-time Mobile Wireless Transmission
Real-time Maritime Wireless Transmission
Live Broadcasting Video Transmission
Public Mobile Communication System
As a conclusion, COFDM modulation solved the difficult problems of "Non-line of Sight" and "Mobile" wireless broadband transmission when speed is over 2Mbps, COFDM can capture videos at high speed and transmit high quality real time videos, make users gain exceptional freedom in news collecting, live broadcasting, real-time monitoring applications.
