1. A method of computing the mean-square-error (MSE) noise of a line in a Digital Subscriber Line (DSL) system, the method comprising:

  • estimating the Hlog function of the line;

    obtaining the power spectral density (PSD) function of the line;

    obtaining the signal to noise ratio (SNR) function of the line;

    computing the MSE noise by subtracting the SNR from the sum of the PSD and Hlog; and

    storing or recording the computed MSE noise in a memory.
