1. A method for estimating error in an input signal, the method comprising the steps of:

  • measuring a magnitude of a plurality of data samples from said input signal;

    defining as an error sample each one of said plurality of data samples when the magnitude of said data sample is at least equal to a first threshold, such that a plurality of error samples are defined;

    calculating a power for each one of said plurality of error samples; and

    specifying an error indicator, said error indicator corresponding to an average of said calculated powers, wherein said error indicator represents the power of the error in said input signal.
