It has strong anti-interference ability and non line of sight diffraction ability
HD 1080P Clear Video quality
Use COFDM ( Coded Orthogonal Frequency Division Multiplexing:Coded orthogonal frequency division multiplexing
The real time image is clear and fluent
It is suitable for integrated applications of aerial image, aerial mapping, power inspection, unmanned vehicle, robot and other wireless image real-time transmission field.
COFDM anti-electromagnetic interference performanceExcellent 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 performanceCan 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.
