Method for recognizing signals using fuzzy classification

摘要

In order to detect signals by using fuzzy-logic classification, the invention calls for the signals to be scanned in time and the scan values compared with fuzzy threshold values using fuzzy-logic laws. For each standard signal in a signal catalogue, strengths are determined which represent the similarity of the signal under examination with the standard signal concerned when the appropriate law is used. In addition, a correspondence factor is calculated, for each standard signal, as the arithmetic mean of all the strengths averaged through all the laws, and the signal under examination is allocated to that standard signal with which the correspondence is the greatest.
