摘要
本文从基于一次观察的双择Bayes接收的工作特性出发,指出了在低信噪比工作情况下,Bayes接收的工作特性中存在着一个不稳定工作点.当接收机的工作状态邻近此不稳定点时,接收机的判决特性将会急剧恶化;这为设计Bayes接收机提供了必须注意的条件.同时本文也讨论了在低信噪比时,接收机避开不稳定工作点的方法.
An unstable position exists in ROC of the Bayes receiver according to the analysis of the ROC of the Bayes receiver based on the single observation.While approaching the neighbourhood of the unstable position the Bayes receiver characteristics are getting worse rapidly, and this result offers an important criterion for designing Bayes receiver when S/ N is low.This paper also presents the method to avoid the above problem.,
