Sample matrix inversion
text:
Sample matrix inversion is an algorithm that estimates weights of an array by replacing the correlation matrix R with its estimate. Using K N -dimensional samples X 1 , X 2 , … , X K , an unbiased estimate of R X , the N × N correlation matrix of the array signals, may be obtained by means of a simple averaging scheme: where H is the conjugate transpose. The expression of the theoretically optimal weights requires the inverse of R X , and the inverse of the estimates matrix is then used for find
