在本文中，分布式无线电场景分析的方法被认为是。无线传感器网络由软件定义终端和认知终端组成，用于对无线场景中存在的空中接口进行分类。两种模式，即跳频码分多址和直接序列码分多址，被确定，采用信号处理技术。时频分析和分布式决策理论。分布式检测的优点被用来提高模式识别模块的性能。误差概率方面的结果得到的概率密度函数的非对称广义和广义高斯函数建模考虑的功能。
In this paper, a distributed approach to radio scene analysis is considered. A Wireless Sensor Network, composed by Software Defined and Cognitive terminals, is used to classify air interfaces present in the radio scene. Two modes, namely Frequency Hopping Code Division Multiple Access and Direct Sequence Code Division Multiple Access, are identified, employing a signal processing technique. Time Frequency analysis, and a distributed decision theory. Advantages given by distributed detection are used to improve the performance of a Mode Identification module. Results in terms of error probability are obtained by modelling the probability density function of considered features as Asymmetric Generalized and Generalized Gaussian functions.
