Abstract:
1. A method for reducing interference in a multiple antenna receiver comprising: receiving signals in each antenna of the multiple antenna receiver; separating each of the signals that were received at each antenna of the multiple antenna receiver into a real part and an imaginary part; filtering each of the separated signals in separate filters to cancel interference and supplying outputs from each of the filters; summing the filter outputs to produce a combined output signal; initially determining filter coefficients in each of the filters utilizing an error signal determined according to a difference of the combined output signal and a reference signal, the reference signal being derived from a training sequence code portion of a communication burst; and wherein the filter coefficients are initially determined according to a weight vector given by a product of an inverse of a time-averaged correlation matrix, Φ, of the separated signals, and a time-averaged cross-correlation vector, z, between the separated signals and the reference signal.
