摘要
通过实验模拟信号方法,标定船舶自动识别系统终端信号失效与场强的相关关系.根据实验样本数据,采用有理分式模型进行数据拟合,获得船舶自动识别系统场强与误包率相关的连续描述,可为基站布设与信号预判提供理论支持.
The relationship between loosing data and field strength in automatic identification system（AIS） terminal was figured out with the help of simulating signal.According to experimental samples,the rational fraction model was used to fit the data,and the correlation between field strength and packet error rate was obtained continuously for AIS,which can provide theoretical support for base-station distribution and signal preprocessing.
