| Abstract: | The modulation technology is one of the key technologies in wireless lasercommunication. At present, intensity modulation or phase modulation is used extensively in wireless laser communication. Frequency modulation system lacking in research is discussed and influence of Doppler effect is analyzed. Using latest technology in optical fiber communication, a scheme of high bit rate FSK optical wireless communication system is proposed, and the system is simulated in Optisystem environment. Influence of parameters such as linewidth of laser, bandwidth of optical filters and transmitting power are ana- lysed by simulation experiments. The research result shows the effectiveness of high bit rate FSK optical wireless communi- cation system. |
