ABSTRACT:
A method for locating an electric level distribution range of sampled signals is provided. The electric level distribution range includes a plurality of reference levels. Firstly, a plurality of initial values are provided. Then, each of the sampled signals is corresponded to one of the plurality of initial values, which is closest thereto. Then, the initial values corresponded are and adjusted by the sampled signals according to a predetermined operation, thereby realizing the reference levels. A method for recovering data from an optical storage medium is also provided. The signals associated with data from an optical storage medium are firstly sampled. Then, an electric level distribution range of the sampled signals is located. Afterwards, the sampled signals are decoded to recover data according to the electric level distribution range.
