<p>A coding method, a decoding method, a coder, and a decoder are disclosed herein. A coding method includes: obtaining pulse distribution about how all the pulses to be encoded on a track are distributed on the track; determining a distribution identifier for identifying the pulse distribution according to the pulse distribution; and generating a coding index that carries the distribution identifier. A decoding method includes: receiving a coding index; extracting the distribution identifier from the coding index, where the distribution identifier identifies the pulse distribution about how all the pulses encoded on a track are distributed on the track; determining the pulse distribution about how all the pulses encoded on a track are distributed on the track according to the distribution identifier; and reconstructing the pulse order on the track according to the pulse distribution.</p> |
