Abstract
A system for processing an RF signal received via a plurality of antenna elements includes a connection arrangement for selecting a sub-set of a given number of RF signals received from the antenna elements as well as a processing arrangement for combining the received RF signals of the selected sub-set into a single RF signal for demodulation. The system includes an RF phasing circuit for producing selective combinations of the received RF signals by applying relative RF phase shift weights to the RF signals that are combined; each combination includes RF signals received from a number of adjacent antenna elements equal to the number of the RF signals in the sub-set to be selected. A radio performance estimator generates for each selective combination of RF signals at least one non-RF radio performance indicator representative of the quality of the RF signals in the combination. A decision block identifies the sub-set of received RF signals to be selected as a function of the one radio performance indicator generated for the selective combinations of the received RF signals.

20. A method of processing an RF signal received via a plurality of antenna elements, comprising:
-
selecting a sub-set of received RF signals from said antenna elements, said sub-set comprising a given number of RF signals; combining the received RF signals of said selected sub-set into a single RF signal for demodulation; selecting said sub-set of received RF signals by; producing selective combinations of said received RF signals from said plurality of antenna elements by applying relative RF phase shift weights to the RF signals that are combined, wherein each combination comprises RF signals received from a number of adjacent antenna elements equal to said given number; generating for each said selective combination of RF signals, at least one radio performance indicator representative of the quality of the RF signals in the combination; and identifying the sub-set to be selected as a function of said at least one radio performance indicator generated for selective combinations of said received RF signals. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
