1. A method for determining a fitting model for a signal, the method comprising:
segmenting a sampled signal based on collected characteristic information of the signal to obtain a plurality of signal segments;
fitting sampling points in the plurality of signal segments using a plurality of fitting models;
acquiring fitted values for a parameter of interest in each signal segment of the plurality of signal segments based on fitting results;
sequentially comparing each of the fitted values for the parameter of interest under each of the fitting models with an acquired measurement value for the parameter of interest; and
determining a final fitting model for reconstructing the sampled signal among the plurality of the fitting models based on comparison results.
