چکیده انگلیسی

Based on several atmospheric channel field tests and analyses, the modulation model of wireless laser communication in hostile weather is investigated, for enhancing the link rate of wireless laser communication. Firstly, the conversion relationship between SER and BER under different conditions is studied. Afterwards, by analyzing atmospheric channel tests result, the importance of atmospheric channel bandwidth was featured during test. On the basis of this, an efficiency pulse state-interval coded modulation is present for the first time and its characteristics are analyzed. In order to verify whether this modulation model is feasible and effective as well as its robustness, a wireless laser communication feasibility experiment in the hostile environments was launched. According to the results, a prospect is pointed out that atmospheric channel properties feedback technique in real time may be a key and precondition in all-weather wireless optical communication.
