ABSTRACT:
A communication device uses its FGU to generate a location signal that can be used by a reference device to calibrate the communication device and to determine the distance of the communication device from the reference device. The communication device: receives, from a reference device, at least one location signal control parameter that defines pulse shape characteristics for a location signal; configures its FGU based on the at least one location signal control parameter; generates a linear first part of a phase-incoherent location signal having the defined pulse shape characteristics by progressively sweeping an output of the FGU over a range of frequencies from a first frequency to a second frequency within a first time period; and transmits at least one iteration of the first part of the location signal.
