Abstract: A system has a plurality of transmission-capable nodes. A method is provided for suppressing interference at a critical sensor situated within this system. The system is first three-dimensionally mapped. Next, phase shifts are estimated for transmissions from the nodes to produce net destructive interference at the critical sensor, based on the three-dimensional mapping of the system. An aggregate electromagnetic signal from the nodes is sensed at the critical sensor. The phase shifts are then adjusted based on the sensed aggregate electromagnetic signal.
