Table 2 for both of the environments that are based on this method of identification of the modulation, dots in Different processing conditions, properly identify 4FSK, QPSK, QAM three signals for longer.

Table 2 for based on two kind of environment, the modulation recognition methods which proposed in view of this article, under the different processing points condition, distinguishes 4FSK, QPSK, the QAM three kind of signal cabins correctly with the time long.

Table 2 is based on two kinds of environments, for modulation classification method, under the conditions of different points, correctly identify either 4FSK, QPSK, QAM signal available longer.
