Abstract
In variants, a method for signal enhancement includes: sampling a set of measurements of a signal source; and determining a SNR-enhanced signal based on the measurements, which, in variants, can include recursively cross-correlating elements for d iterations S200; and determining a SNR-enhanced signal from the cross-correlation outputs. The method functions to determine a SNR-enhanced signal representative of the signal source. The method can optionally include determining an analyte parameter based on the SNR-enhanced signal.
Claims20
A system, comprising:
- a nuclear magnetic resonance (NMR) device, configured to sample a plurality of signals from an analysis target;
- and
- a processing system, configured to:
- recursively cross-correlate signals within unique sets of at least two distinct signals with non-overlapping datapoints from the plurality of signals;
- and
- determine a parameter of the analysis target based on outputs of the cross-correlations.
The system of claim 12, wherein the aggregated outputs collectively form a signal-to-noise ratio (SNR)-enhanced signal, wherein the processing system is configured to transform the SNR-enhanced signal to a frequency domain and determine the parameter based on the transformed SNR-enhanced signal.
A method, comprising:
- determining a plurality of signals associated with an analysis target;
- for at least a first iteration, cross-correlating signals within unique subsets of at least two distinct signals determined from the plurality of signals;
- determining a processed signal based on outputs of the cross-correlations;
- and
- determining parameters of the analysis target based on the processed signal.
