H-530AHD wireless video transmission system,UseCOFDM（Coded Orthogonal Frequency Division Multiplexing：CodeOrthogonal Frequency Division Multiplexing (OFDM) modulation technology with transmission bandwidthNarrow (2-8MHz), strong anti-multipath interference ability and anti-multipath fading ability. It can realize real-time transmission of high-quality images under non-line-of-sight (NLOS) and high-speed motion conditions.
System adoptionH.264 Digital Video Coding Standard, Outputhigh definitionHD1080P quality, resolution 1920*1080, 720P, and standard definition.
It is suitable for large UAV, UAV, UAV, special robot and other image transmission fields.
Anti-EMI Performance of COFDM:
It has excellent performance against frequency selective fading or narrowband interference and interference between signal waveforms. It has strong anti-fading ability through the joint coding of various subcarriers. In single carrier systems (e.g. digital microwave, spread spectrum microwave, etc.), a single fading or interference can cause the whole communication link to fail, but in multi-carrier systems.In COFDM system, only a small part of subcarriers will be interfered, and these subchannels can also use error correction codes to correct errors, to ensure the low bit error rate of transmission.
COFDM resistancemultipath fadingperformance:
It can effectively counteract the interference between signal waveforms and is suitable for high-speed data transmission in multipath environment and fading channel. When frequency selective fading occurs in the channel due to multipath transmission, only the subcarriers falling in the frequency band depression and the information they carry are affected, while the other subcarriers are not damaged, so the system bit error rateVery low (less than or equal to)10-6）。
