1. A system for the correction of multipath errors in a telecommunication device location system, the system comprising:

  • a receiver to receive data transmitted from a remote transmitter located at an unknown distance from the receiver; and

    an analyzer to analyze data associated with the received data and to generate location data related to a location of the receiver, the analyzer further calculating a correction factor based on a measured signal criterion to generate corrected location data;

    wherein the receiver generates a correlation pulse when the received data is correlated to a stored data pattern, the signal criterion being a pulse width of the correlation pulse;

    wherein the signal analyzer models the correlation pulse as a quadratic equation having a plurality of coefficients, the coefficients being determined by amplitude values of the correlation pulse at predetermined times.
