Long range COFDM video transmitter advantages:
- 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 interference with the multi-carrier technique (COFDM). Compared to the single carrier, the multi-carrier is inherently resistant to time delay and has a strong multipath capability. With joint coding of subcarriers & frequency diversity of the channel, the system’s performance is improved. Therefore, the COFDM wireless system is suitable for multi-path environments and fading high-speed audio video data transmission channels.
- 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 the mobile vehicle, UAV to ground station, UAV to vessle…
Description:
NLOS COFDM wireless video link transmitter (KP-HSA510) is a new design ultra-low latency COFDM digital wireless video transmitter. It is designed with 3 video ports, HD, SDI, and CVBS on the transmitter, perfect for analog or digital cameras.
With 4th generation COFDM, narrow-band, and H.264 encoder technology as its code, KP-HSA510 sends high definition images ideal for establishing rugged wireless video links in different environments, like mobile and urban environments. The compact design and low consumption make this HD transmitter enable accurate long-range HD video transmission.
