发明名称 Multi-user detection in mobile terminal for reducing interference
摘要 Interference cancellation in a mobile terminal ( 4 ) in telecommunication systems like Direct Sequence-Code Division Multiple Access systems or DS-CDMA systems can be improved by providing the mobile terminal ( 4 ) with a multi-user detector ( 41,42,43 ). These multi-user detectors require the spreading codes of other mobile terminals ( 2,3,5,6,7,8,9 ), which spreading codes are available in base stations ( 1 ) and thus need to be sent to said mobile terminal ( 4 ). By further transmitting power information of other mobile terminals ( 2,3,5,6,7,8,9 ) to the mobile terminal ( 4 ), a selector ( 52 ) can make an intelligent selection in said mobile terminal ( 4 ) and select the most important spreading codes thereby reducing the computational complexity. By locating a selector ( 22 ) in a base station ( 1 ), an intelligent selection can also be made in said base station. Preferably a selection is made per antenna sector and/or in dependence of antenna sectors, in which case direction information of other mobile terminals ( 2,3,5,6,7,8,9 ) need to be used.
