ABSTRACT:
An interference signal removal system includes interference signal estimating means for estimating an interference signal contained in a received signal based on the received signal and a result obtained by removing an interference signal from the received signal, interference signal removing means for removing from the received signal the interference signal estimated by the interference signal estimating means; and interference signal estimation controlling means for storing the interference signal estimation result of the interference signal estimating means in memory and controlling the interference signal estimation by the interference signal estimating means so as to estimate an interference signal contained in the received signal based on a past interference signal estimation result stored in memory.
