Patent ID: 8669900

Claim:
A system for reducing multipath error when determining a location of a stationary or near stationary position, comprising: a plurality of antennas arranged in positions fixed with respect to the stationary or near stationary position; a combining unit for combining signals from the plurality of antennas and outputting a compound received signal, the compound received signal including a multipath component, wherein the combining unit comprises a plurality of variable attenuators each receiving a signal from one of the plurality of antennas, each variable attenuator attenuating and outputting the received signal, and wherein the combining unit further comprises a mixer for combining and averaging the outputs of the plurality of variable attenuators and outputting the compound received signal; a processor for processing the compound received signal including the multipath component, wherein multipath component in the compound received signal is reduced during the processing; and a location determining unit for determining a location of the stationary or near stationary position based on the processed compound received signal with the multipath component reduced.
