Patent ID: 8249534

Claim:
A method for identifying components in a telecommunication system, which method comprises the steps: representing a uniform linear array, ULA, antenna, having at least two antenna elements, by an array factor polynomial, the polynomial comprising at least two terms, each term having a certain weight (w k ); setting said weights (w k ) to desired values such that a desired antenna radiation pattern corresponding to a desired array factor polynomial is acquired for the ULA antenna; wherein the method comprises the steps: changing the desired weights such that a number of sets of desired weights (w k ) is acquired, such that the ULA antenna scans a spatial portion, a certain scan corresponding to a certain set of desired weights, and the number of scans at least being equal to the number of antenna elements in the ULA antenna; analyzing a received signal (h 0 ) obtained from said scans, the received signal (h 0 ) being represented by a received array factor polynomial comprising at least two terms, each term having a certain received weight, such that a received set of weights is acquired, the received set of weights being constituted by the desired set of weights (w k ) scaled and rotated, the received array factor polynomial further being parameterized by at least one pole; and using each corresponding set of desired weights (w k ) and received weights to determine the pole parameterization.
