Two-way voice wireless image transmission system

The high-definition vehicle-mounted two-way voice wireless video transmission system adopts (
coded orthogonal frequency division multiplexing) modulation technology, which has a narrow transmission frequency band and strong anti-multipath interference capabilities, and can realize non-line-of-sight high-speed movement conditions Real-time transmission of high-quality images. The two-way intercom function makes on-site command more flexible.
The system adopts
digital video coding standard to output high-definition picture quality with resolution up to* (downward compatible and standard definition).
Widely used in military reconnaissance, border defense, patrol, public security (including fire protection, forest fire and traffic police), civil air defense emergency, water conservancy and flood control, environmental protection monitoring, power inspection, railway rescue, maritime law enforcement, urban management and law enforcement, construction site/dock/oil field monitoring, television broadcast, health and epidemic prevention, etc., or emergency command of emergencies . It is suitable for real-time mobile transmission of video in various complex geographical environments such as seas and mountains in urban areas.


Suitable for mobile surveillance vehicle command center. It can also be used as a relay device to extend the transmission distance.
Excellent performance against frequency selective fading or narrowband interference and interference between signal waveforms. It has strong anti-fading capabilities through joint coding of each sub-carrier. In a single-carrier system (such as digital microwave spread spectrum microwave) a single fading or interference can cause the entire communication link to fail, but in a multi-carrier system only a small part of the sub-carriers will be interfered and these sub-channels can also use error correction codes. To perform error correction to ensure a low bit error rate in transmission. The technology has excellent performance in overcoming reflections (multipath interference, overcoming the motion Doppler effect and combating various interferences), so it can transmit reliably in high-speed relative motion.

The channel utilization rate is very high
This is particularly important in a wireless environment with limited spectrum resources. When the number of subcarriers is large, the spectrum utilization rate of the system tends to /.

Application form of vehicle-mounted equipment
Suitable for individual vehicle command centers. Due to the large power of the equipment, it can carry out large-scale mobile high-definition image transmission on-site and can transmit kilometers under line-of-sight.
