1. A subject monitoring system for determining physiological information of a subject, comprising:

  • a sensor configured to generate an intensity signal, wherein the sensor detects light attenuated by the subject; and

    processing equipment coupled to the sensor, wherein the processing equipment is configured to;

    determine a value indicative of a physiological rate of the subject;

    calculate a first cross-correlation sequence based on the intensity signal and a first reference waveform;

    calculate a second cross-correlation sequence based on the intensity signal and a second reference waveform; and

    determine whether to qualify the value indicative of the physiological rate of the subject based on the first cross-correlation sequence and the second cross-correlation sequence.
