Product Description

COFDM 1080P wireless video transmission system for live broadcast
Key Features

1. Small size and lightweight, the hot shoe hole is very easy to install;
2. Excellent anti-interference ability and non-line-of-sight diffraction ability;
3. Clear picture quality, HD 1080P resolution;
4. Real-time images are clear and smooth;
5. Use COFDM(Coded Orthogonal Frequency Division Multiplexing: Coded orthogonal frequency division multiplexing);
6. Specially developed for mobile phone live broadcast, director monitoring and other film and television live broadcast industries
7. Externally embedded double F970 battery hanging plate,Make it last longer;
8. Self heat dissipation performance of the high-performance all-aluminum alloy shell is more stable.

COFDM anti-electromagnetic interference performance:
Excellent against frequency selective fading or narrowband interference and interference between signal waveforms. It has strong anti-fading capability through joint coding of each subcarrier.In a single carrier system (eg digital microwave, spread spectrum microwave, etc.), a single fading or interference can cause the entire communication link to fail, but in a multi-carrier COFDM system, only a small fraction of the subcarriers are subject to interference, and these The channel can also use error correction code for error correction to ensure low error rate of transmission.
COFDM anti-multipath fading performance:
Can effectively combat interference between signal waveforms, suitable for high-speed data transmission in multipath environments and fading channels.When frequency selective fading occurs in the channel due to multipath transmission, only the subcarriers that fall in the band recess and the information carried by them are affected, and the other subcarriers are not damaged, so the overall BER performance of the system is better.
