Military Backpack Portable COFDM Transmitter Two Way Voice Intercome 256 - bit AES Encryption

Military Backpack Portable COFDM Transmitter Two Way Voice Intercome 256 - bit AES Encryption

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.

COFDM Video transmitter Anti-multipath fading:
It can confront signal waveform interference effectively; suitable for multi-path environment and fading channel high-speed data transmission. When the frequency selective fading appear in the channel because of multi-path transmission, only the sub-carrier, which fell over the band depression, and the information carried will be affected. Other sub-carriers will not be affected. Thus, the system total error rate performance will be much better.

Portable COFDM Transmitter System Application:

This military backpack system is special for man-portable transmitter enter into the area of the incident to gather information and signal transmission when in the condition of heavy obstacles, such as many building barriers, severe electromagnetic interference, remote mountain town or other harsh environments, which cause command vehicle can’t directly reach the site and forced to parked in vicinity.
