Product Details
COFDM Video Transmitter Wireless 4k RF Signal Handheld Radio
Vehicle Mounted HD 1080p Military Frequencies
1080P HD transmitter is a powerful HD transmit system,using the
core of mobile communication technology COFDM(multi-carrier
modulation technique),which can transmit good quality and stable
full-HD digital video signal under the condition of high speed moving and heavy building blocks in city environment. The HD1080P wireless video transmitter supports stereo balance audio input and narrow-band transmission system.
Features
- Strong interference:COFDM wireless transmitter is effectively against the multipath
interference of signal waveform with the COFDM modulation. When the
frequency selective fading occurs due to multipath transmission in
the channel, only the subcarriers in the band depression and the
signal carried by them are affected. The other subcarriers are not
affected. Therefore, the overall bit error rate of the system is
lower.
- Anti-multipath fading: COFDM wireless audio video transmitter is effectively against the
interference with the multi-carrier technique (COFDM). Compared to
the single carrier, multi-carrier inherently resistant to time
delay and has strong multipath capability. With joint coding of
subcarriers & frequency diversity of the channel, the system’s
performance is improved. Therefore, COFDM wireless system is
suitable for multi-path environment and fading channel high-speed
audio video data transmission.
- LOS & NLOS operation: with strong penetration, strong diffraction & strong
anti-interference, COFDM wireless system is suitable for high-speed
mobile wireless transmission in NLOS &LOS operation without
servo stability control assistance, such as on UAV to mobile
vehicle, uav to groun station, UAV to vessle...
