1. A method comprising:

  • receiving an input signal;

    producing a target vector from the input signal;

    constructing a plurality of inverse weighting functions based on the target vector;

    evaluating an error value associated with each of the plurality of inverse weighting functions to produce a fixed codebook code-vector; and

    generating a codeword representative of the fixed codebook code-vector, where the codeword is for use by a decoder to generate an approximation of the input signal.
