Claim Text:
1. A method for reconstructing data, comprising: acquiring, by a receive end, a self-correlation function of a root raised cosine filter coefficient and a fading factor of each antenna of channel estimation; constructing, by the receive end, an L-dimension matrix of the self-correlation function according to the antenna, where L is the number of valid paths found by said each antenna; processing, by the receive end, 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, by the receive end, received data according to the estimate value of the actual fading factor to obtain reconstructed data used for interference cancellation; wherein the processing the 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 comprises: performing a solving operation on the result of superposing the L-dimension matrix of the self-correlation function and the fading factor of each antenna to obtain the estimate value of the actual fading factor of the each antenna; performing inversion on the L-dimension matrix of the self-correlation function to obtain an L-dimension inverse matrix of the self-correlation function; and performing deconvolution processing on the result of superposing the fading factor of each antenna and the L-dimension inverse matrix of the self-correlation function to obtain the estimate value of the actual fading factor of the each antenna.
