COFDM Video transmitter Anti-electromagnetic interference performance:
It has superior performance against frequency selective fading or narrow bandwidth interference and signal waveform interference. It has strong anti-fading ability, through each subcarrier joint coding. In single carrier system(digital microwave, spread spectrum system, etc), single decline or interference will result in all communication link failure. But in multiple carrier COFDM system, only a few subcarriers will be interfered What’s more, these sub-channel can adopt ECC to correct error, to guarantee the transmission low error rate.
Compatible UAV Drone Video Receiver
LinkAV-C204 Mini Wireless Receiver is a compact digital diversity receiver in a durable, compact and lightweight housing. It can receive multiple different frequencies of transmitter audio signal, support HDMI and CVBS interface with external display and USB storage.
It can realize the AV transmission between the transmitter and the mini receiver LinkAV-C204.
Adopting the advanced foreign technology of diversity reception, to overcome the simulation technology and conventional modulation technology under multipath reflection image transmission, and keep real-time transmit high quality SD/HD image under high speed mobile and NLOS conditions, particularly suitable for using in complex environment
