Abstract
A method for controlling an adaptive antenna array ( ) is provided and includes receiving a plurality of signals, each signal including a series of signal data symbols ( ) and signal non-data symbols ( ) divided into symbol transmission units with the signal non-data symbols ( ) disposed among the signal data symbols ( ) in each unit and each signal related to the other signals of the plurality of signals as reflections of an original signal. The method also includes separating the signal non-data symbols ( ) from the signal data symbols ( ), and comparing the signal non-data symbols ( ) to a set of known non-data symbols. The method further includes determining a set of weights according to the comparison of the signal non-data symbols ( ) to the set of known non-data symbols, the weights to be combined with the signal data values ( ) to limit the effect of interference on the signal data symbols ( ). An adaptive antenna array ( ) is also provided including a weight calculator ( ) including a program which controls the weight calculator ( ) to perform the comparing ( ) and determining steps ( ) of the method discussed above.
