Ultraviolet communication system based on BPSK subcarrier intensity modulation
Ultraviolet communication is a novel communication mode, which delivers massages through the scattering of ultraviolet in the atmosphere. Modulation technology is one of key technical challenges in ultraviolet communication. So far, the ultraviolet communication system mostly uses pulsed optical intensity modulation, but this technique cannot improve the performance of ultraviolet communication system. Thus, BPSK subcarrier intensity modulation is introduced to the ultraviolet communication system based on the analysis of the basic principle of the BPSK subcarrier intensity modulation technology. In the single scattering channel model, the ultraviolet communication system based on BPSK subcarrier intensity modulation technology is simulated and compared with a variety of other intensity modulation technique. The simulation results show that the BPSK subcarrier intensity modulation technique outperforms the traditional OOK and PPM modulation techniques in terms of bit error rate, information rate and other properties.
