Abstract:
A coding method, a decoding method, a coder, and a decoder, where the coding method includes obtaining the pulse distribution, on a track, of the pulses to be encoded on the track, determining a distribution identifier for identifying the pulse distribution according to the pulse distribution, and generating a coding index that includes the distribution identifier. The decoding method includes receiving a coding index, obtaining a distribution identifier from the coding index, wherein the distribution identifier is configured to identify the pulse distribution, on a track, of the pulses to be encoded on the track, determining the pulse distribution, on a track, of all the pulses to be encoded on the track according to the distribution identifier, and reconstructing the pulse order on the track according to the pulse distribution.

Claim (Index 7):
A method for coding of an audio signal sample, comprising:\n obtaining, by a coder, a pulse distribution of pulses to be encoded on a track of the audio signal sample, wherein the pulse distribution comprises a quantity of pulse positions N, a vector P(N)={p( 0 ), p( 1 ), . . . , p(N\u22121)} indicating a distribution of the pulse positions on the track, and a quantity of pulses in each of the pulse positions; determining, by the coder, a first index from a lookup table according to the quantity of the pulse positions N, determining, by the coder, a second index by using the following permutation formula: I \ue89e \ue89e 2 = C M N - C M - p \ue8a0 ( 0 ) N + \u2211 n = 1 N - 1 \ue89e \ue89e [ C M - p \ue8a0 ( n - 1 ) - 1 N - n - C M - p \ue8a0 ( n ) N - n ] , wherein p( 0 )<p( 1 )< . . . <p(N\u22121), p( 0 ) \u2208 [0, M\u2212N], p(n) represents a position serial number of n th  position having pulses, p(n) \u2208 [p(n\u22121)+1, M\u2212N +n], C refers to calculating a combination function, \u03a3 refers to summing, and M is a total quantity of positions on the track; determining, by the coder, a third index according to the quantity of pulses in each of the pulse positions, wherein the third index corresponds to the quantity of pulses in each of the pulse positions; and generating, by the coder, a combined index for the track, wherein the combined index comprises the first index, the second index, and the third index.
