1. A method, comprising:
receiving, via a mobile device, a wide-band transmission transmitted from at least one base station of three or more base stations, wherein the wide-band transmission includes distributed traffic symbol portions, distributed pilot symbol portions, and intermittent punctured pilot symbol portions, wherein the intermittent punctured pilot symbol portions include pilot symbols transmitted randomly throughout the wide-band transmission; determining, via the mobile device, a first path portion of the wide-band transmission based at least in part on the intermittent punctured pilot symbol portions, wherein the first path portion of the wide-band transmission is associated with a first time delay and a second path portion of the wide-band transmission is associated with a second time delay; determining, via the mobile device, a distance between the mobile device and the at least one base station based at least in part on the first time delay; and determining, via the mobile device, a location of the mobile device based at least in part on the determined distance; wherein the wide-band transmission has a power-delay profile at the mobile device; and wherein determining the first path portion includes evaluating a first part of the power-delay profile that is earlier than a second part of the power-delay profile that relates to the second path portion. |
