MAXIMUM LIKELIHOOD FUNCTION BASE METHOD FOR ESTIMATING LOCATION AT THE RADIO ENVIRONMENT INCLUDING THE POSITION ERROR AND APPARATUS THEREOF OF THE REFERENCE DEVICE CAPABLE OF THE EXACT LOCATION ESTIMATE
MAXIMUM LIKELIHOOD FUNCTION BASE METHOD FOR ESTIMATING LOCATION AT THE RADIO ENVIRONMENT INCLUDING THE POSITION ERROR AND APPARATUS THEREOF OF THE REFERENCE DEVICE CAPABLE OF THE EXACT LOCATION ESTIMATE
PURPOSE: A maximum likelihood function base method for estimating location on a radio environment including position error of a reference device and its apparatus is provided to accurately presume the location of a blind device by reflecting the error of a reference device and by presuming the location of a blind device.;CONSTITUTION: A transceiver(100) transmits and receives fixed signal with reference devices. A position-related information storage(104) comprises an arrival measuring unit(110) and a storing part of position information(112). The arrival measuring unit measures travel time about each reference device by using measure related information. The storing part of position information stores the location received from each reference device. A location estimate part(106) presumes the location of the blind device by using the measured arrival time and the location.;COPYRIGHT KIPO 2010
