METHOD AND APPARATUS FOR RANGING OR POSITIONING, BASED ON AN ELECTRIC WAVE DELAY TIME ACCORDING TO STRENGTH OF A RECEIVED SIGNAL AND A SEPARATION DISTANCE BETWEEN TTRANSCEIVERS

摘要

PURPOSE: A method and an apparatus for ranging or positioning are provided to estimate a distance by time diversity, space diversity, and balance effect between antennas using multiple antennas which capable of switching per each transceivers.;CONSTITUTION: A multiple antenna(210) has a linear array structure of arranging antenna on a straight line or a planar grid array structure which is regularly arranged on a coplanar plane. A switch(220) selects one antenna of a plurality of antennae. A transceiver(230) transmits and receives a packet through one antenna selected by the switch.;COPYRIGHT KIPO 2010
