COFDM Technique Advantages
Strong interference: Itu COFDM wireless transmitter is effectively against the multipath interference of signal waveform with the COFDM modulation. When the frequency selective fading occurs due to multipath transmission in the channel, only the subcarriers in the band depression and the signal carried by them are affected. The other subcarriers are not affected. Karena itu, the overall bit error rate of the system is lower.
Anti-multipath fading: COFDM wireless audio video transmitter is effectively against interference with the multi-carrier technique (COFDM). Compared to the single carrier, the multi-carrier is inherently resistant to time delay and has a strong multipath capability. With joint coding of subcarriers & frequency diversity of the channel, the system’s performance is improved. Karena itu, COFDM wireless system is suitable for multi-path environments and fading channel high-speed audio video data transmission.
KEHILANGAN & NLOS operation: with strong penetration, strong diffraction & anti-interferensi yang kuat, COFDM wireless system is suitable for high-speed mobile wireless transmission in NLOS &LOS operation without servo stability control assistance, such as on UAV to the mobile vehicle, UAV to ground station, UAV to vessel…

Introduce:
As its lightweight and long-range distance make it widely used in public security, polisi bersenjata, api, field troops, and other military departments and transport, bea cukai, minyak, pertambangan, air, listrik, keuangan, and other important national departments.
This system has the advantages of high sensitivity, strong anti-interference ability and penetrating ability, high transmission rate, and strong stability. It provides an ideal solution for the construction of emergency communication systems such as command, menyelamatkan, pengintaian, and field combat.
