  • Method of an apparatus for beam reduction and combining in a radio communications system
    Patent number: 6470192
    Abstract: Recently, interference rejection combining techniques have been proposed which can significantly increase the performance of the uplink in C/I limited environments. However, as with many signal processing techniques, calculation complexity can be performance issue. Thus, according to exemplary embodiments of the present invention, the noise cross-correlation matrix used in interference rejection combining is reduced by applying beamforming and signal combining techniques. In this way, the benefits of interference rejection combining are obtained while reducing the processing complexity and freeing processor resources for other activities.
