The OFDM Modulation in the Problem of Automatic Modulation Recognition
In this paper is explored the problem of including OFDM modulation into the set of digital modulation types of radio signals using the multilayer neural network. Recognition is conducted using the cumulant features with known carrier frequency. The test results show that the inclusion OFDM modulation into the set of digital modulation types does not affect on the recognition probabilities of other types, while the recognizing probability of OFDM type is almost 100 %.
Keywords: OFDM modulation, digital modulation recognition, moments, cumulants, Gaussian noise, multilayer neural network, characteristic function, IQ data
