In the identification process of modulated signal based cyclic spectrum, it is chief to be synchronized for the received signal.The article focuses on the reception signal which is not synchronized.When uniform distribution variable delay exists, it will not have cyclostationary, namely it is converted into a stable signal, which limits the usable range of cyclic spectrum identifying signals.Meanwhile, in this situation, through extracting characteristic parameters, simulation shows that the method is perfect for modulation identification under the condition that SNR is 0-50dB.
