Patent ID: 7058145

Claim:
A remote station apparatus comprising: a multi-element antenna configured to receive signals from at least one transmitter and to output highly correlated signals from the respective transmitter; a controller configured to receive the highly correlated signals, to determine a spatial signature, including amplitude, angle of arrival and phase for each signal, to estimate a complex covariance matrix and to combine the correlated signals to reproduce the signal transmitted from a selected one of the at least one transmitter; and wherein the controller further comprises a weighting factor engine configured to determine a set of weighting factors for each of the at least one transmitter signals in response to the spatial signatures of the received signals and said complex covariance matrix, whereby said weighting factors may be determined in accordance with the following equation: w=((R−Rs) −1 )c, where w is the weighting factor, c is an estimate of said complex spatial signature, R is said complex covariance matrix, and Rs is the matrix formed by taking the outer product of said c with c-hermitian conjugate.
