Low power consumption, excellent heat dissipation, working temperature≤45℃; 14. LinkAV Patent,Integrated design built-in battery and outside core power interface; 15. Power stability, 21 to 35 dBm adjustable dynamic power; 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.
