Abstract: This disclosure provides a device and a system for retrofitting a vehicle for unmanned operation. The system can have a navigation computer that can provide commands to a plurality of actuators for manipulating the onboard controls of a vehicle. The navigation computer can receive input from one or more remote operators and from a variety of sensors. The plurality of actuators can include a steering actuator that surrounds a steering column or a steering column housing to engage with a steering wheel of the vehicle. The steering actuator can have tongs that engage the steering wheel. The tongs can be coupled to an inner gear ring that can rotate within an outer housing of the steering actuator. Rotation of the tongs can interact with and move the steering wheel in response to commands from the navigation computer.

Abstract: The disclosure provides systems and methods for interference reduction in wireless communications. The method can include receiving a composite signal having multiple overlapping constituent signals and a noise floor. The noise floor can have at least one interfering coherent signal. The system can characterize and synthesize the multiple overlapping constituent signals without a priori know. The method can include receiving a secondary input comprising the at least one interfering coherent signal. The method can include canceling the interfering coherent signal from the noise floor. The method can include outputting the first signal and the second signal having a reduced noise floor.
