ABSTRACT:
A method and apparatus for performing stream weighting in a spatial-division multiple access communication system is provided herein. During operation the base station receiver receives channel information from mobiles (also known as users or nodes) and calculates transmit antenna weights that that maximize the power delivered to each mobile while allowing for a small amount of crosstalk to exist between users. Information or data is transmitted to the nodes utilizing the appropriate stream weights. By allowing tolerable amounts of cross talk, the coherent gain to the desired SDMA user can be increased, and thus the overall performance is improved.
