COFDM Video ReceiverVideo Transmitter schematic diagram
  • Easy to carry It has strong anti-interference ability and non line of sight diffraction ability
  • Low delay ≤300ms
  • The system adopts H.264/MPEG-2 digital video coding standardClear picture to 720*576@25fps
  • Use COFDM(Coded Orthogonal Frequency Division Multiplexing:Coded orthogonal frequency division multiplexing)
  • Diversity dual antenna reception, so that the real-time image clearer and smoother
  • Applicable to the scene of the scene to monitor the car and other places. The volumesmall may do to camouflage equipment forensics, air operations, UAV image transmission wireless image transmission.
  • Supporting bidirectional voice
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.
