An encoding method, a decoding method, an encoder and a decoder are provided. The encoding method includes: obtaining distributing information of all pulses on tracks which need encoding; determining distributing signs for marking said distributing information based on said distributing information, generating encoding indexes including said distributing signs. The decoding method includes: accepting the encoding indexes, extracting the distributing signs from said encoding indexes, said distributing signs are used to mark the distributing information of all pulses on tracks which need encoding, determining the distributing information of all pulses on tracks which need encoding based on said distributing signs, and restructuring pulse sequences on tracks based on said distributing information. |
