Abstract
A receiver system and method for determining the location of a device in a wireless network having a plurality of transmitters is provided. The method includes receiving a signal at the device, transforming the received signal into a time-domain signal having a characteristic, and computing a range of the device from each of the plurality of transmitters based on the characteristic. Additionally, the method includes determining the location of the device based on the computed ranges. In certain embodiments, the characteristic may be a time of arrival, time difference of arrival, or a signal strength, and the wireless network is a DTV broadcasting network.
