Patent ID: 6934323

Claim:
A CDMA receiver for receiving transmission signals transmitted from a first plurality of users and putting out message signals included in the respective transmission signals, the CDMA receiver comprising: a second plurality of antennas; radio portions, fed by respective antennas, for providing reception signals derived from said respective antennas; matrix calculation means for performing a matrix calculation by using said reception signals to provide at least a common correlation matrix; adaptive array antenna signal processing portions provided for respective users, each adaptive array antenna signal processing portion being supplied with said reception signals from said radio portions; and detectors, provided for respective users, for detecting said message signals from output signals of said adaptive array antenna signal processing portions, wherein each of said adaptive array antenna signal processing portions comprises: a second plurality of matched filters, each of said matched filters being configured to match a spreading code of each user to provide a despread signal; means for calculating a weight vector by using a result of said matrix calculation; a second plurality of multipliers for weighing said despread signals from said matched filters with respective elements of said weight vector to provide weighed despread signals; and means for combining said weighed despread signals into one of said output signals associated with each user.
