Abstract (en)
A coding-decoding method using a mulipulse analysis-by-synthesis excitation technique comprises, in the decoding phase, cascaded long-term and short-term synthesis filterings. The lag and gain of the long-term synthesis and the excitation pulses are determined during the coding phase within the analysis-by-synthesis procedure in two subsequent steps, in the first of which the lag and the gain are determined, while in the second the positions and the amplitudes of the excitation pulses are determined. The invention concerns also the device performing the method.
