Abstract
Embodiments of the present invention provide a method and an apparatus for reconstructing data. The method includes: acquiring a self-correlation function of a root raised cosine filter coefficient and a fading factor of each antenna of channel estimation; constructing an L-dimension matrix of the self-correlation function according to the antenna; processing a result of superposing the L-dimension matrix of the self-correlation function and the fading factor of each antenna to obtain an estimate value of an actual fading factor of the each antenna; and reconstructing received data according to the estimate value of the actual fading factor to obtain reconstructed data used for cancellation. In the embodiments of the present invention, a process of performing interference cancellation for data reconstruction is closer to an actual sending process and closer to an originally sent signal, thereby improving cancellation efficiency and reducing interference.
