ABSTRACT:
The method and system provides an improvement in signal to noise plus interference without utilizing a calculated covariance matrix or calibrated antenna array, and does not require knowledge of the array geometry. The system utilizes the cross correlation of the output of each antenna element to estimate a weight vector for resolving a signal in a multiple simultaneous source environment.
