Abstract
An interference cancellation method performed by a receiver includes: determining a strong interference code channel among all code channels that carry a received signal, and determining a signal that corresponds to the strong interference code channel to be a strong interference signal, wherein the received signal has been matched filtered. The method further includes obtaining a reconstructed strong interference signal based on the determined strong interference signal and using a system matrix, performing the interference cancellation for the received signal using the reconstructed strong interference signal, to obtain the signal without interference. The strong interference signal can be reconstructed using the system matrix, and the interference cancellation can be performed for the received signal using the reconstructed strong interference signal. The complexity of inverting the matrix is reduced and the performance is enhanced by reducing the order of the matrix, and thus increasing the efficiency of cancelling the interference.
