MULTI-USER DETECTION FOR ANTENNA ARRAY RECEIVERS |
摘要 |
The present invention relates to radio communication antennas and in particular relates to multi-user detection for CDMA antenna array receivers. A reverse link (mobile to base) of a cellular direct sequence code division multiple access system is provided which increases system capacity whilst avoiding system complexity. The invention provides a method of signal detection which is based on the partitioning of users into equivalence classes by beam-forming with subsequent standard multi-user detection techniques applied within each class. Computation techniques are simplified and processing time can be considerably reduced. Furthermore, the capacity of a conventional receiver may be improved by employing multi-user detection techniques. These techniques are particularly useful for systems which involve large numbers of users. A method of operation is also disclosed.
