Abstract
Methods and devices for distance measuring/ranging, as well as location measurements both in 2D and 3D are presented. More specifically, the methods and devices are for determining the time of arrival of a radio frequency signal. A method of determining a time of arrival of a radio frequency signal in a receiving device as received from a transmitting device includes receiving a radio frequency signal, determining a first phase. The first phase is defined as a phase of the received radio frequency signal. The method also includes obtaining a second phase. The second phase is defined as a phase of a reference radio frequency signal. The method also includes determining the time of arrival of the radio frequency signal based on comparing the first and second phases.
