Patent ID: 7161974

Claim:
A method for combining a direct sequence spread spectrum signal comprising signal components that each may be characterized with a space variable (i) and a time variable (j), comprising: a. despreading said signal components; and b. determining in one step a set of combining coefficients (w i, j ) from said signal components (x i, j ) using a Minimum Mean Square Error combining method that considers said space and time variables of the signal components in parallel according to: W 2D MMSE =ξR −1 xx r xp R xx =E ( XX *) r xp =E ( Xp *), where X is an L dimensional column vector comprising signal components (x i, j ), W 2D MMSE is an L dimensional column vector comprising combining coefficients (w i, j ), L is an integer greater than zero, and p is an expected pilot symbol.
