Abstract  Abstract

A method of indexing positions and pulse amplitudes in an algebraic encryption and decryption code for efficient coding and decoding of a sound signal, in which: - the encryption and decryption code comprises a set of combinations of amplitude / pulse position; - each pulse amplitude / position combination defines a number of different positions and comprises both zero amplitude pulses and non-zero amplitude pulses, assigned to respective positions of the combination, and - each non-zero amplitude pulse assumes one of the plurality of possible amplitudes, and wherein said indexing method comprises: forming a set of at least one track of said pulse positions, in which the position of each non-zero amplitude pulse of each amplitude combination / Pulse position is restricted to a track of said set; - indexing, according to a first procedure, mentioned in the following as procedure 1, the position and amplitude of a pulse of nonzero amplitude only when the position of said pulse of nonzero amplitude is located on a track of said set; - indexing, according to a second procedure, mentioned in what follows as procedure 2, the positions and amplitudes of two non-zero pulses only when the positions of said two pulses of non-zero amplitude are located on a track of said set , and - when the positions of a number X of pulses of non-zero amplitude are located on a track of said set, in which X> _3: - divide the positions of said track into two sections; - use another procedure associated with said number X, mentioned in the following as procedure X, to index the positions and amplitudes of said X pulses of non-zero amplitude, said method X comprising: - identify in which of the two track sections each pulse of nonzero amplitude is located; - calculate sub-indices of said X pulses of non-zero amplitude using procedures 1 and 2 in at least one of said track sections and in the full track, and - calculate an index of position and amplitude of said X pulses of non-zero amplitude by combining said sub-indices.
