The present invention discloses an interference cancellation method and apparatus, wherein the method includes: determining a strong interference code channel among all code channels that carry a received signal by a receiver, and determining a signal that corresponds to the strong interference code channel to be a strong interference signal, wherein the received signal is a signal that has been matched filtered; obtaining the reconstructed strong interference signal based on the determined strong interference signal reconstructed from a system matrix by the receiver; performing the interference cancellation for the received signal by utilizing the reconstructed strong interference signal, and obtaining the signal whose interference have been cancelled by the receiver. According to the present invention, the strong interference signal can be reconstructed by utilizing the system matrix, and the interference cancellation can be performed for the received signal by utilizing the reconstructed strong interference signal. The complexity of the operation for the matrix inversion can be reduced and the performance of the apparatus can be improved by reducing the order of the matrix, and thus the efficiency of the process for cancelling the interference can be increased.
