在本文中，我们讨论了90分钟的周期性信号（90-MPS）的相位和睡眠的主观质量之间的关联在睡眠实验中的多个科目使用传感器的唤醒支持系统。当使用快速傅立叶变换（FFT）和滤波从传感器数据中提取90-MPS时，周期的变化表现为90-MPS的相移。因此，有必要关注提取的90-MPS的相位，并分析其与主观质量之间的关联。使用FFT选择交感神经系统指数，该指数具有来自睡眠期间传感器数据的90分钟时间段的数据。此外，通过使用滤波器提取90-MPS，并使用Oguri-Shirakawa-Azumi睡眠调查表，中年和老年版本（OSA-MA）分析唤醒时间的90-MPS相位与睡眠质量之间的关联。当睡眠质量最高时，分布集中在OSA-MA五个类别中四个类别的90-MPS III期，不包括刷新（OSA-MA 4）。已经证实，当醒来阶段为III时，可以获得最高质量的睡眠。
: In this paper, we discuss the association between the phase of a 90-minute periodic signal (90-MPS) and the subjective quality of sleep in sleep experiments of multi-subjects using sensors for the wake-up support system. When 90-MPS is extracted from the sensor data using Fast Fourier Transform (FFT) and filtering, the change in period appears as a phase shift of 90-MPS. Therefore, it is necessary to focus on the phase of extracted 90-MPS and analyze the association between that and subjective quality. The sympathetic nervous system index that has data with a clear 90-minute period from the sensor data during sleep was selected using FFT. Furthermore, a 90-MPS is extracted by using the filter, and the association between the phase of 90-MPS at the wake-up time and quality of sleep using the Oguri-Shirakawa-Azumi sleep inventory, middle-aged and aged version (OSA-MA) was analyzed. When quality of sleep was the highest, the distribution was centered on phase III of 90-MPS at four categories excluding refreshing (OSA-MA 4) among the five categories of OSA-MA. It has been confirmed that the highest quality of sleep can be obtained when the waking up phase is III.
