Details of COFDM video transmitter
1080P COFDM wireless video transmitter is a mini 1080i full HD video transmitter.
COFDM wireless video transmitter is with the core of mobile communication technology COFDM (multi-carrier modulation technique), which can transmit high quality and stable full-HD digital video signal in high speed mobile condition and heavy building blocks.
COFDM HD video transmitter is with H.264 encoding format, stereo balance audio input and narrowband.

COFDM Technique Advantages

1. Strong interference: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. Therefore, the overall bit error rate of the system is lower.
2. Anti-multipath fading: COFDM wireless audio video transmitter is effectively against the interference with the multi-carrier technique (COFDM). Compared to the single carrier, multi-carrier inherently resistant to time delay and has strong multipath capability. With joint coding of subcarriers & frequency diversity of the channel, the system’s performance is improved. Therefore, COFDM wireless system is suitable for multi-path environment and fading channel high-speed audio video data transmission.
3. LOS & NLOS operation: with strong penetration, strong diffraction & strong anti-interference, 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 mobile vehicle, uav to groun station, UAV to vessle...
