Abstract
System and method for reducing interference to existing devices. A preferred embodiment comprises specifying a frequency range for a set of dummy signals, specifying a clipping function to ensure that the set of dummy signals do not exceed a maximum power constraint, incorporating a least squares solution for computing the set of dummy signals into the clipping function, and iterating the clipping function until a terminating condition is reached. The use of the clipping function limits the magnitude of the dummy signals, to ensure that dummy signals do not exceed a maximum power constraint.
