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 1):
A method for coding 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 the pulses in each of the pulse positions; determining, by the coder, a first index 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 the pulses in each of the pulse positions, wherein the third index corresponds to the quantity of the pulses in each of the pulse positions; and generating, by the coder, a coding index that comprises the first index, the second index, and the third index.
