摘要
船舶大气光通信中存在着通信信道狭窄的问题,为此提出软件无线电技术在船舶大气光通信中的应用研究。采用Nyquist采样定理对船舶大气光通信信道信号采集频率进行确定,以确定的信号采集频率对信道信号进行采集与处理,以上述得到的信号为基础建立船舶大气光通信信道模型,已建立的通信信道模型为基础推算出船舶大气光通信信道扩展算法,通过信道扩展算法的执行实现了软件无线技术在船舶大气光通信中的应用,并对信道进行扩展。实验结果显示,使用软件无线电技术的船舶大气光通信信道数据量比未使用的高出30T,充分说明设计的软件无线电技术具备极高的有效性。
There is a problem of narrow communication channel in ship atmospheric optical communication.Therefore,the application of software radio technology in ship atmospheric optical communication is proposed.The Nyquist sampling theorem is used to determine the acquisition frequency of the ship atmospheric optical communication channel signal,and to determine the acquisition frequency of the signal to collect and process the channel signal.Based on the above-mentioned signals,the model of the ship atmospheric optical communication channel is established.Based on the established communication channel model,the channel expansion algorithm of the ship atmospheric optical communication channel is deduced.The implementation implements the application of software wireless technology in ship atmospheric optical communication,and expands the channel.The experimental results show that the data volume of the atmospheric optical communication channel using software radio technology is 30 T higher than that of the unused one,which fully demonstrates that the designed software radio technology has very high effectiveness.
