Patent ID: 8666347

Claim:
A device for reducing interference in wireless signals comprising: a plurality of antennae; a signal detector; a processing unit; a signal modifier; and at least one stage connected to said plurality of antennae, said at least one stage being at least one of: a field nulling stage connected to said plurality of antennae, wherein one of the plurality of antennae is a receiving antenna, wherein another of the plurality of antennae is a transmitting antenna, and wherein said field nulling stage comprises a return signal receiving circuit and a communications antenna signal delay element; and a signal cancelling stage connected to said plurality of antennae, and wherein said signal cancelling stage comprises a signal combiner for combining a first antenna signal modified with respect to at least one of amplitude and phase and a second antenna signal modified with respect to at least one group delay, wherein said at least one stage, said signal detector, said processing unit and said signal modifier provide a signal-to-noise-ratio enhanced signal to a receiver.
