Patent ID: 6907272

Claim:
An array receiver system, for receiving signals from a plurality of transmitting users, comprising an array of antenna elements ( 22 / 1 , . . . , 22 / 10 ) and a receiver having a plurality of receiver sections ( 12 0 , . . . , 12 7 ), each corresponding to a different one of the users, the receiver sections each having a signal processing unit ( 16 0 ) for processing and combining a subset of signals from the antenna elements to produce a received signal for the corresponding user, the receiver further comprising switching means ( 18 0 ) for selecting a plurality of different subsets of signals from the antenna elements for processing for the signal processing unit ( 16 0 ), each subset consisting of a predetermined number of said signals, each signal processing means serving to control the switching means to change the signals comprising the subset of signals used by the corresponding receiver section in dependence upon a measure of the potential performance of that receiver section with different subsets of said plurality of signals, said measure being based upon the combined subset of signals.
