Abstract
A data recovery method includes the following steps. Firstly, plural sampling values are classified into a first group, a second group, a third group and a fourth group. A first channel estimation value and a second channel estimation value are generated according to the sampling values of the second group and the third group. A judging step is performed to judge whether a first sampling value of the first group is lower than the first channel estimation value or a second sampling value of the fourth group is higher than the second channel estimation value. If the judging condition is satisfied, a polarity of the first sampling value or the second sampling value is changed and then the plural sampling values are outputted. If the judging condition is not satisfied, the plural sampling values are directly outputted.
