Abstract:
In an antenna array, signals may be manipulated to increase coherency at certain locations (beamfocusing) and reduce or cancel the signals at other locations (nulling). This is accomplished by multiplying the signals received or transmitted by the set of antennas by a weight vector that is generated by determining a covariance matrix based on a vector representing signals at the set of antennas, vectors representing the desired beamfocusing and nulling locations, and a desired nulling depth.

Claim (Index 1):
A method of beamfocusing and nulling signals carried by electromagnetic waves, the method comprising:\n determining a first vector representing signals received at each of a plurality of disparate antennas, wherein each of the plurality of disparate antennas is configured with electromagnetic transmission and reception components and a signal processing component, and wherein each disparate antenna is geographically separate from each other disparate antenna; determining a weight vector based on the first vector, a nulling location, and a beamfocusing location; and applying the weight vector to signals at the plurality of disparate antennas, wherein applying the weight vector to the signals at the plurality of disparate antennas comprises multiplying signals transmitted or received by the plurality of antennas by the weight vector, thereby achieving beamfocusing at the beamfocusing location and nulling at the nulling location; wherein determining the weight vector comprises generating a covariance matrix using a beamfocusing vector representing a magnitude and a phase of signals received at the beamfocusing location, and a nulling vector representing a magnitude and a phase of signals received at the nulling location; and wherein each of said plurality of disparate antennas is configured on a separate and distinct mobile radio and at least one of said plurality of disparate antennas is of a first antenna type including an omnidirectional type, a dipole type and an array type, and another of the said plurality of disparate antennas is of a second antenna type different than the first antenna type.
