海上无线电通信中信息的可信度研究

Research on Reliability of Information in Radio Communication at Sea

介绍了海上无线电通信中采用的无线电线路的特性,以及可信度估算的两种模型,阐述了可信度动态估算算法的流程图,分析了噪声模型、信息模型和可信度控制电路,最后以调频信号通过短波信道传输为例,说明了海上无线电通信中信息的可信度控制的工作原理。

This paper introduces the speciality of radio line in radio communication at sea and two models of reliability evaluation, describes the flow diagram of arithmetic of reliability dynamic evaluation, analyses the noise model, communication model and the control circuit of reliability, finally,taking FM transfers HF channel as an example,this paper shows operating principle of reliability control of information in radio communication at sea.
