COFDM anti-electromagnetic interference performance

It has excellent performance against frequency selective fading or narrow-band interference and interference between signal waveforms. It has strong anti-fading ability through the joint coding of each subcarrier. In a single carrier system (such as digital microwave, spread spectrum microwave, etc.), a single fading or interference can cause the entire communication link to fail, but in a multi-carrier COFDM system, only a small part of the subcarriers will be interfered with, and these subcarriers The channel can also use error correction codes for error correction to ensure a low bit error rate for transmission.

COFDM anti-multipath fading performance

      It can effectively combat the interference between signal waveforms, and is suitable for high-speed data transmission in multipath environments and fading channels. When frequency selective fading occurs in the channel due to multipath transmission, only the subcarriers that fall in the band depression and the information they carry are affected, and the other subcarriers are not damaged, so the overall bit error rate performance of the system is better many.

Application form of individual equipment

       Applicable to individual soldiers ~ vehicles, individual soldiers ~ command centers. Because the equipment has large power and long distance, it can carry out large-scale mobile high-definition image transmission on site.

Solution Application

The overall transmission path: individual soldiers ~ communication command vehicles ~ local command centers ~ networks to provincial and municipal command centers. The front-end staff carries the transmitting equipment to transmit live video and audio signals to the communication command vehicle; the communication command vehicle acts as a relay relay to extend the wireless signal to the local command center; the local command center can directly connect a channel of audio and video signals to the monitor for Real-time monitoring and debugging command, the other way is directly transmitted to the national provincial and municipal command centers through the metropolitan area network or wide area network; the command center can directly connect audio and video signals to the monitor for real-time monitoring, and at the same time can use the network monitoring and PC to browse audio Video and video operations.
