Patent ID: 8879433

Claim:
A method for full duplex wireless communication comprising the steps of: creating a canceling self interference signal using active noise cancelation in radio frequency (RF) transmission by using a plurality of transmit antennas and feeding the plurality of transmit antennas with an RF signal for enabling part of said RF signal to be destructively combined at a receive antenna; attaining full-duplex simultaneous in time and overlapping in space wireless transmission and reception on same frequency band responsive to the step of creating the canceling self interference signal; wherein the plurality of transmit antennas are grouped into two sets: a first group of driving transmit antennas from which the RF signal comprising a signal of interest is transmitted and a wireless tandem group of associated tandem transmit antennas that generates and transmits the canceling self interference signal at the receive antenna based on the signal of interest and a channel between the transmit and receive antennas; and wherein a distance between a transmit antenna of the first group and an associated tandem transmit antenna of the wireless tandem group is an integer multiple of λ plus λ/2, λ being a wavelength of a carrier frequency.
