ITERATIVE RECEPTION METHOD AND ITERATIVE RECEIVER

摘要

An iterative reception method and iterative receiver in a mobile communication system are provided. In order to remove inter-cell interference of a signal that is iteratively received in a multi-cell environment, a hard determination value of different cells excluding a specific cell is used. In addition, in order to remove interference of different user in the specific cell caused by inaccurate channel estimation, the hard determination value of the specific cell signal is used. Further, in order to improve reception performance of the iterative receiver that performs the interference by using the hard determination value, channel estimation is iteratively performed on the iteratively received signal by using a hard determination value of the specific cell to update a channel estimation value.
