POLARIZATION REUSE AND BEAM-FORMING TECHNIQUES FOR AERONAUTICAL BROADBAND SYSTEMS
First Claim
1. An apparatus for enhancing aeronautical broadband communication, the apparatus comprising:
- a first antenna configured to communicate using a signal orientation corresponding to a first polarization;
a second antenna configured to communicate using a signal orientation corresponding to said first polarization; and
at least one processor configured to combine the signals received from said first antenna and said second antenna in a proportion based on an algorithm for selecting a signal according to a first signal quality measurement selected from one of a signal to interference plus noise ratio (SINR), a signal to interference ratio (SIR), or a signal to noise ratio (SNR).

Abstract
Aeronautical broadband communication is enhanced by providing an apparatus having a first antenna configured to communicate using a signal orientation corresponding to a first polarization, and a second antenna configured to communicate using a signal orientation corresponding to a second polarization, where the second polarization has at least one characteristic difference from the first polarization. Additional antennas may be used, where multiple antennas share one polarization, and multiple other antennas share a different polarization, and signals from like-polarized antennas are combined for beam-formation.
