Based on the statistics only in the method of identification mode signal-to-noise ratio, QPSK AND QAM SIGNAL correctly identify the probability of 80 per cent or higher in the signal-to-noise ratio is proper identification signal 4FSK probability of 98 per cent. can reach

Based on the statistical pattern recognition methods only then in the signal-to-noise ratio situation, QPSK and the QAM signal correct identification probability achieved above 80%, when signal-to-noise ratio the 4FSK signal correct identification probability may achieve 98%.

Pattern recognition method based on statistics only in the case of signal to noise ratio, QPSK and QAM signals recognition probability above 80%, 4FSK in SNR signal recognition probability can be reached 98%.
