Abstract: PURPOSE: A multiuser interference cancellation receiver for a TDD-CDMA(Time Division Duplex-Code Division Multiple Access) system and a method for controlling the interference cancellation are provided to perform interference cancellation for signals having high power values even when differences of signal power values are wide among users, so as to minimize errors in the detection of user signals having low signal power values. CONSTITUTION: A data extractor(100) extracts data from received signals and outputs the extracted data. A signal delay part(200) delays the signals outputted from the data extractor(100) during a predetermined time, and outputs the delayed signals. An interference cancellation selection part(300) extracts midamble signal channels from received original signals, to select and output users of the subject of the first interference cancellation. The first step interference cancellation block(400) receives data of the received signals from the data extractor(100), to perform the first parallel interference cancellation for the selected users of the first interference cancellation subject and output reproduction signals. And the second step interference cancellation block(500) receives data of the received signals delayed during the predetermined time and outputted from the signal delay part(200), to perform the second parallel interference cancellation using the first reproduction signals outputted from the first step interference cancellation block(400).
