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

  • an antenna capable of detecting telecommunications signals and generating detected electrical signals as a result thereof;

    a receiver coupled to the antenna to receive the detected electrical signals;

    an energy detector to analyze the received signals and to generate a correlation pulse when the received signals match a stored reference signal;

    a timer to determine a time of arrival of the correlation pulse;

    an analyzer to calculate a pulse width of the correlation pulse and to apply a correction factor to the time of arrival based on the pulse width to generate a corrected time of arrival.
