| Abstract: | Classification of digital modulation, the signal characteristics of the phase of the cycle will cause the phase volume and reduce overlapping signals in the received RF digital modulation automatically correct classification probability. According to the principle of minimum mean square, a phase modulation and phase modulation signal classification features as well as 2PSK and MPSK classification. Experimental results show that this phase characteristics of communication signals based on the automatic modulation classification algorithm has strong robustness,it has reached a high recognition of different types and roll-off factors of the pulse shaping filter and a high symbol rates. |
