Abstract

A communications system may be characterized by a system error variance because the error variance provides an indication of signal corruption in the system. By strategically adding a secondary sensor to the communications system, system characteristics may be altered so that the system error variance is reduced. A system and method are presented, wherein a secondary sensor is configured to receive a disturbance effect and produce a filtered slave signal as a function of the disturbance effect. The filtered slave signal is configured to alter the characteristics of the communications system and thereby reduce system error variance.
