1. A method for full duplex wireless communication comprising the steps of:
- creating a canceling self interference signal using a passive noise cancellation; and
attaining full-duplex simultaneous in time and overlapping in space wireless transmission and reception on a same frequency band responsive to the step of creating said canceling self interference signal,wherein said passive noise cancellation comprises analog noise canceller circuits in multiple stages,wherein a residual of the self interference signal in an output signal of each of said multiple stages is cancelled by subtracting an attenuated version of a transmitted signal from said output signal of each of said multiple stages, andwherein an average power of the output signal at each stage of the multiple stages is minimized.
