| 摘 要： | 为了增强激光通信对信道的适应性，在香农理论的基础上对大气调制模型展开了研究。首先从差错的角度推导大气光通信系统误符号率与误码率的转换关系；接着通过分析大气信道下光通信的香农极限通信速率，指出大气信道带宽是影响激光通信的重要技术参数。进而提出了脉冲状态间隔调制编码方式并分析其结构特点；最后通过恶劣环境下的通信实验验证PSIM的可行性和大气信道带宽的重要性，指出信道特性实时反馈将是实现全天候激光通信的前提。

| Abstract: | Based on the Shannon classical communication theory,the atmospheric modulation model of wireless laser communication was investigated for enhancing wireless laser communication adaptability of the atmospheric channel.Firstly,the conversion relations of SER and BER was discussed,from error theory perspectives analysis atmospheric optical wireless communications.Afterwards,by analyzing Shannon limit communication rate of wireless laser communication in atmospheric channel,the importance of atmospheric channel bandwidth gradually came out.On the basis of this,an efficiency pulse state-interval coded modulation was present and its characteristics were estimated.Finally,the feasibility of the PSIM and the importance of atmospheric channel bandwidth to wireless laser communication were proved by wireless laser communication experiment in the hostile environments,At the end,a prospect was pointed out that atmospheric channel properties feedback technique in real time might be a key and precondition in all-weather wireless optical communication. |
