Patent ID: 8396438

Claim:
A method, comprising: weighting signals from multiple receive antennas utilizing a combination of maximal ratio combining (MRC) and interference nulling; modifying a covariance matrix corresponding to interference to include at least one configurable parameter according to s new =(1−λ)s+λd, where s is an original value and represents eigenvalues of the covariance matrix when the covariance matrix is factorized into a diagonal form, s new is a modified value and represents eigenvalues of the modified covariance matrix when the modified covariance matrix is factorized into the diagonal form, λ is the at least one configurable parameter, and d is a desired value for a variable and represents desired choices for the eigenvalues of s; selecting a value for the at least one configurable parameter, generating respective weights for each receive path utilizing the modified covariance matrix as a function of the value of the at least one configurable parameter for the interference nulling, applying the respective weights to corresponding signals from the multiple receive antennas; and merging the weighted signals to yield an output signal.
