Abstract
The invention provides for a cab signaling apparatus and method for use on board a railway vehicle propelled on a set of spaced rails by a traction motor. The cab signaling apparatus may reduce a noise component within a signal having a primary cab signal component and reduce a cab signal component within a signal having a primary noise component. The cab signaling apparatus may further include an adaptive filter to cancel the noise component within the signal having a primary cab signal component without specialized tuning of the cab signaling apparatus. The cab signaling apparatus may include a false code monitor for identifying a true cab signal code and a track signal monitor for identifying a true cab signal in the presence of noise.
