METHOD AND SYSTEM FOR ACTIVE NOISE CANCELLATION IN CAB SIGNAL SYSTEMS

摘要

Methods and systems for a cab signal system are provided. The system includes at least one inductive pickup coil assembly, and a cab signal receiver electrically coupled to the at least one inductive pickup coil assembly. The receiver is configured to receive amplitude and phase information associated with an electromagnetic noise signal portion and receive amplitude and phase information associated with a cab signal portion received by the at least one inductive pickup coil assembly. The receiver is further configured to determine a phase difference between electromagnetic noise signal portion and the cab signal portion and combine the electromagnetic noise signal portion and the cab signal portion based on the phase difference such that an amplitude of the electromagnetic noise signal portion is facilitated being reduced.
