Modulation recognition methods presented for single signal case are not valid for multiple signals' case, including decision theory based and statisticpatternrecognition based methods.
In this paper, the problem of statisticpatternrecognition converted into the problem of the best hypothesis test of risk which can be used to judge whether the machine is in normal operation or not.
