<p>A method of encoding the excitation pulse parameters when determining the positions of a given number (N=j+N1, N2) of excitation pulses within a speech frame in a linear predictive speech encoder, where the positions are determined by a combination of two known methods. Firstly, a plurality of calculation stages (j) are performed to determine the positions of the excitation pulses in accordance with the first known method, whereafter a plurality of calculation stages (N1, N2, ..., NL) are performed to determine the positions of the excitation pulses in accordance with the second method each with a starting point from one of a plurality of positions (mi, mk, mr) calculated in accordance with the first method.</p> |
