Bandwidth Reduction of Sleep Information.
TLDR
Several features of heart rate which contain sleep information are computed and analysis of variance is used to indicate the suitability of these measures in the pattern recognition of sleep stages from heart rate data.Abstract:
: Many important space and military missions require maximal alertness which is dependent on adequate amounts of rest and sleep. In order to study sleep-wakefulness patterns in realistic space and military situations, it is necessary to monitor the level of arousal with simplified reliable band-limited devices. The limited time bandwidth available for the transmission of sleep information necessitates the development of a technique for data compression. This report describes the possibility of extracting sleep information from heart rate data. Several features of heart rate which contain sleep information are computed and analysis of variance is used to indicate the suitability of these measures in the pattern recognition of sleep stages from heart rate data.

Computer sleep stage classification using heart rate data.
TL;DR: This paper explores the possibility of using discriminant analysis and Bayes classification procedures to determine sleep stage using only heart rate data, and correlates the computerized sleep pattern with respect to the EEG hand-scored pattern.

Detection of cyclic sleep phenomena using instantaneous heart rate.
TL;DR: This analytical tool was designed to aid in the detection of sleep cycles, or more specifically, the rhythmic transitions from REM+ (awake Stages 1 and REM combined) to NREM (Stage 2, 3 and 4 combined) over a normal night of sleep.
