Patent ID: 6970722

Claim:
A method of wireless communication comprising: exchanging wireless signals between at least one remote client and a directional antenna array associated with a wireless network, wherein the directional antenna array includes a plurality of antenna elements; locating angles associated with directions of arrival for wireles signals from each client with respect to the antenna array; determining values for weighting factors of wireless signals for each of the respective plurality of antenna elements, so as to create predetermined phase differences between the signals of the plurality of antenna elements, wherein the determining values for the weighting factors comprises sampling baseband signals from each antenna element, so as to obtain a representation of sampled signals from a particular client; using the predetermined phase differences to direct at least one null toward at least one source of interference, so as to avoid signal interference; wherein the sampled signals are used to buld up a covariance matrix R; and wherein the sampled signals X have vector components x 0 , x 1 , x 2 , . . . x n that are expressed in matrix form such that X={x 0 x 1 x 2 . . . x n }, and wherein the covariance matrix R is built up such that R=XX H where R is the direct product of X, and X H is the Hermitian matrix of X.
