This article considers the problem of radio signal classification based on spectral features formed from complex low-frequency signal samples (in-phase and quadrature components). The main goal of the research is to build a single machine learning model capable of effectively identifying the type of signal by its spectral characteristics. The signal is represented using the power spectral density (PSD), calculated by the Welch method, as well as additional statistical and frequency-energy features that reflect the amplitude-phase structure of the signal. The model structure is proposed and the processes of its training, validation and testing are implemented. An analysis of the influence of spectral decomposition parameters on classification quality is conducted. The experimental results demonstrate that the combined use of spectral and statistical features allows achieving high accuracy in recognizing various types of radio signals. The proposed approach can be applied in practical systems for automatic radio frequency spectrum analysis and signal detection in complex electromagnetic environments.
