Abstract
A method for estimating a parameter includes: generating an optical signal, the optical signal modulated via a modulation signal; transmitting the modulated optical signal from a light source into an optical fiber, the optical fiber including a plurality of sensing locations disposed along the optical fiber and configured to reflect light; receiving a reflected signal including light reflected from the plurality of sensing locations; and combining, in parallel, each of a plurality of reference signals with the reflected signal to estimate a value of the parameter.

A method for estimating a parameter, the method comprising:
- generating an optical signal, the optical signal modulated via a modulation signal;
- transmitting the modulated optical signal from a light source into an optical fiber, the optical fiber including a plurality of sensing locations disposed along the optical fiber and configured to reflect light;
- receiving a reflected signal including light reflected from the plurality of sensing locations;
- and
- combining, in parallel, each of a plurality of reference signals with the reflected signal to estimate a value of the parameter.
A system for estimating a parameter, the system comprising:
- a light source in optical communication with an optical fiber, the light source configured to generate an optical signal, the optical fiber configured to receive the optical signal and including a plurality of sensing locations disposed along the optical fiber and configured to reflect light;
- a modulator configured to modulate the optical signal via a modulation signal;
- a detector configured to receive a reflected signal including light reflected from the plurality of sensing locations;
- and
- a processor configured to combine, in parallel, each of a plurality of reference signals with the reflected signal to estimate a value of the parameter.
