ABSTRACT:
An interference cancellation circuit which can remove the interference signal caused by other systems and contained in received signals. The interference signal can be cancelled even if the interference signal is not directly obtained or plural interference signals exist, or the interference signal is a wide band signal or raster interference simply by receiving two signals which have passed through different transmission paths, combining the main signals contained in each of the received signals in a manner to offset each other to the extract interference signal, and removing the interference signal component from the received signal based on the expected interference signal.
