1. A system for detecting and correcting non-stationary noise present on an input data signal comprising:

  • a detector module based on Gram Schmidt orthogonalization, receiving the input data signal and producing as output a correction enable signal indicating when a correction is required;

    a corrector module receiving the input data signal and correction enable signal and producing a corrected data signal as output; and

    a reliability estimator and selector module receiving the corrected data signal and the input data signal and producing an output signal which is the more reliable of the input data signal and the corrected data signal.
