Fuzzy decision tree and multilayer neural network for digital modulation recognition


Dam Van Nhich – Post-graduate Student, Department IIST FREC, Moscow Institute of Physics and Technology (State University). E-mail:

The article solves the problem of digital modulation recognition of radio signals based on the using fuzzy decision tree and multilayer neural network. Recognition performed with the basic types of digital modulation 2-PSK, 4-PSK, 8-PSK, 2-FSK, 8-QAM, 16-QAM, 64-QAM. Features for the entrance in the neural network are cumulants. Performance testing methods carried out on one and the same database. The best result shown by using the multilayer neural network.
