Abstract

See full text

A method for recovering a data required to have n consecutive and repetitive bits is disclosed. The data is obtained by converting a sample value sequence into a binary sequence according to a preset value and the data having n-1 consecutive first-level bits and two second-level bits immediately adjacent to two end bits of the n-1 consecutive first-level bits, respectively. The method corrects one of the two second-level bits, which has a corresponding sample value closer to the preset value than the other, into another first-level bit to obtain n consecutive first-level bits. In addition, a device for recovering a data to be decoded is also disclosed.
