1. A residual signal coding apparatus, comprising:

  • a transformer for transforming time-domain residual signals into a frequency domain to output transform coefficients;

    a band splitter for splitting the transform coefficients into a predetermined number of bands to output the transform coefficients on a per-band basis;

    a pulse searcher for searching the transform coefficients for the respective bands to select an optimal pulse and output parameters of the optimal pulse; and

    a pulse quantizer for quantizing the parameters of the optimal pulse.
