Patent ID: 7830952

Claim:
A CDMA wireless communication receiver apparatus, comprising: an input for providing a communication signal which has been transmitted over a wireless communication link and which includes interference and a plurality of communication signal components; an interference statistic unit coupled to said input for producing in response to said communication signal a set of data indicative of a statistical characteristic of said interference, wherein said set of data is an inverse correlation matrix associated with said interference; a plurality of signal processing paths that correspond respectively to said plurality of communication signal components, each of said signal processing paths coupled to said interference statistic unit, each of said signal processing paths receiving said set of data for sharing among each of said signal processing paths in common, and each of said signal processing paths applying to said shared set of data a signal processing operation associated with the corresponding communication signal component; and a plurality of channel estimators respectively associated with the communication signal components and coupled to said input for providing respective channel estimate vectors that are respectively associated with the communication signal components, and a plurality of vector adjusters respectively associated with the communication signal components, each said vector adjuster coupled between the associated channel estimator and the associated signal processing path, said vector adjusters applying respective adjustments to the associated channel estimate vectors to produce respectively corresponding adjusted vectors, and each said signal processing path combining the associated adjusted vector with said inverse correlation matrix to produce a weight vector for use in combining signals that have been despread for the associated communication signal component.
