Method for a Canceling Self Interference Signal Using Active Noise Cancellation in the Air for Full Duplex Simultaneous (In Time) and Overlapping (In Space) Wireless Transmission & Reception on the Same Frequency band

摘要

A method for full duplex communication includes creating a canceling self interference signal using active noise cancelation in the air by using a plurality of transmit antennas and feeding the plurality of antennas with an RF signal in so that part of said RF signal is destructively combined at a receive antenna, and attaining full-duplex simultaneous in time and overlapping in space wireless transmission and reception on same frequency band responsive to the step of creating a canceling self interference signal.
