Abstract:
In a communications system including a first communications station and a second communications station, said first communications station having an antenna array for generating an antenna beam pattern used for transmission of information signals to said second communications station, a method for adaptively forming said beam pattern comprising:estimating data transmitted from said second communications station to said first communications station based on a signal received at said first communications station;based on said estimated transmitted data, estimating a receive channel from said second communications station to said first communications station;computing a desired component of a statistical characterization of said received signal over time based on said receive channel estimate;computing an undesired component of said statistical characterization of said received signal over time based on a characterization of interference taking advantage of knowledge of said estimated transmitted data and said received data;developing a beam pattern weight vector based on said desired component and said undesired component of said statistical characterization; andforming said beam pattern in accordance with said beam pattern weight vector.
