1. A subject monitoring system for determining physiological information of a subject, comprising:
- a sensor configured to generate at least one sample of physiological data, wherein the sensor detects light attenuated by the subject; and
processing equipment coupled to the sensor, wherein the processing equipment is configured to;
determine one or more initialization values based on the at least one sample of physiological data;
generate a window of data that comprises the one or more initialization values and one or more samples of the physiological data; and
process the window of data to determine a physiological parameter.

Abstract
A physiological monitoring system may determine physiological information, such as physiological rate information, from a physiological signal. The system may generate a window of data, and determine physiological information based on the window of data. The generated window of data may include one or more samples of physiological data, from the physiological signal, and one or more initialization values. The initialization values may include random numbers, noise values, sample values, scaled values thereof, or a combination thereof.
