Sleep stage prediction method, device and equipment based on physiological signals

The invention relates to the technical field of signal processing, in particular to a sleep staging prediction method, device and equipment based on physiological signals, various signals can be obtained without attaching a large number of sensors to the head, the chest and other positions of a human body, and only the physiological signals of a user need to be detected. A heart impact signal and a respiration signal are separated from the physiological signal, a cardio-pulmonary coordination sequence and a body movement artifact detection sequence of the user are constructed based on the heart impact signal and the respiration signal, a decision fusion sequence is constructed based on the cardio-pulmonary coordination sequence and the body movement artifact detection sequence, and a stage prediction module is used for performing stage prediction according to the decision fusion sequence and the stage prediction sequence. The detection mode is convenient and fast, expert evaluation is not ...
