Abstract:
A communication system for receiving, from among a plurality of signals each of which includes one of a plurality of identifier components, a signal having a preselected one of said plurality of identifier components, said system comprising:a. an antenna having a configurable beam pattern;b. a focusing subsystem for causing said configurable beam pattern to be focused on the largest of said plurality of signals;c. an identifier subsystem for determining which of said plurality of identifier components is included in said largest signal; andd. a nulling subsystem which, in the event that the identifier component identified by said identifier subsystem is not said preselected one of a plurality of identifier components, causes modification of said configurable beam pattern to the effect that a null is formed in the direction of said largest signal, and said beam pattern is refocused on the next largest signal.
