256 - bit AES Encryption UAV Drone COFDM Receiver Long Rang Images Transmission
Mainly transfer way: UAV~Car control station~ Control
center~Internet to different city control center.
UAV assemble mini devices, transfer air live video signal to the
communications station, or a local command centre. Local display
monitor, storage command center can direct send the audio and video
to real-time monitoring, dispatch. Other video way directly through
the metropolitan area network or Wan transfers to the provinces and
command center; to access PC browsing management, videos and so on.
For mobile or stationary application;
HD ("High Definition") and SD ("Standard Definition") compatible;
Automatically adjusts to Video Formats
High image quality,with clear,stable and smooth image
Small size, light weight and rugged
The Model LinkAV-C204 of COFDM mini UAV receiver adopted the simulation technology and conventional modulation technology under multipath reflection image transmission, and it can keep real-time transmit high quality HD image under high speed mobile and NLOS conditions, particularly suitable for use in complex environment.

As air robot, UAV can use for spy on, monitor, geodetic surveying and remote control ,etc, in the In the military field and for civil use. It is mainly used for the acquisition of high resolution, describing objects set form 2D or 3D images. High speed transmission of image has become an important restriction problem of the UAV application, because of the high resolution image data in large amount, with the ground resolution is increased, the amount of image data need to be transmitted in a geometric increase in the number of data, code rate is also growing rapidly.
In recent years, the rapid development of COFDM technology, the technology makes the equipment capable of wireless transmission of high volume data in high speed movement, and effectively solves the OFDM technology for channel flat fading (the carrier amplitude obeys Rayleigh fading) deficiency, this technique is very suitable for UAV image real-time transmission.
Introduced a COFDM wireless transmission equipment.
