Алгоритми модуляції ЕКГ–сигналів на основі ЛЧМ та ФКМ

Abstract

The study examines the role of modulated signals in radio engineering systems and their application for biomedical signal processing. It is shown that the modulation method significantly affects the signal's spectral characteristics, its noise robustness, and the efficiency of subsequent analysis. Special attention is given to linear frequency modulation (LFM) and phase-coded modulation (PCM), which are widely used in radar, communication, and remote sensing systems. An approach is proposed for generating and modulating synthetic ECG signals using LFM and PCM algorithms. This approach enables the study of cardiac electrophysiological processes using radio engineering signal processing methods. The obtained results can be applied in the development of telemedicine systems, portable medical devices, and embedded biomedical signal monitoring systems.
