Abstract
Systems, methods, and computer program products for determining a location from non-line-of-sight (NLOS) signals are described. A processor can determine that multipath interferences of a signal reaching a receiver through different paths that are close in lengths may be mistakenly interpreted as additional time shift, (e.g., additional time delay or, in some cases, time advance) of the signal in calculating a timing of the signal. The processor can determine the possible differences between path lengths and then determine an amount of the additional time shift. The processor can determine a shift correction to remove effects caused by the additional time delay from the timing calculation.
