摘要

A modulated signal is demodulated to obtain a modulation signal. The modulated signal is contained within an input signal. A periodic time segment sequence is defined having a plurality of ordered time segments. Signal values are acquired, from the input signal, during each ordered time segment. Signal values acquired during each ordered time segment are combined with signal values acquired during the same ordered time segment over multiple periods of the periodic time segment sequence. The modulated signal is demodulated by executing mathematical steps on the combined signal values to obtain the modulation signal.

1. A method for demodulating a modulated signal to obtain a modulation signal, the modulated signal contained within an input signal, the method comprising:
defining a periodic time segment sequence having a plurality of ordered time segments; acquiring signal values, from the input signal, during each ordered time segment; combining signal values acquired during each ordered time segment with signal values acquired during the same ordered time segment over multiple periods of the periodic time segment sequence; and demodulating the modulated signal by executing mathematical steps on the combined signal values to obtain the modulation signal.
