A Sequential Search Algorithm with Signal-Selected Pulse Amplitudes

"With the objective of reducing computational complexity in algebraic code-excited linear predictive (ACELP) coders, this paper describes the use of a low-complexity sequential search algorithm with signalselected pulse amplitudes. The described algorithm was inserted in both the ETSI GSM-AMR and ITU-T G.729 codecs, and when compared to some standard algorithms it showed to be quite efficient while causing only a slight degradation in the voice quality."
