摘要
The invention of the transmitter by using a time difference of the radio signals transmitted from a transmitter reaches a plurality of receivers relates to an RFID-based location estimation system in a mobile environment that allows to estimate the location, and a transmitter for periodically transmitting a radio signal; And a receiver for receiving a wireless signal transmitted from the transmitter; The radio signal is transmitted from the transmitter using the time difference reaching the plurality of the receiver calculates the distance difference between the distance between the transmitter and each receiver has received the radio signal from the transmitter, respectively, using a predetermined calculated distance difference and generates a plurality of objects with the position values create a cluster consisting of the generated object, the position with the smallest fitness value of the objects that make up the cluster, but designated as an excellent year, and best to improve communities through improved by including a positioning engine to determine the position of the superior to that improved in the transmitter, the positioning engine in consideration of the degree of error in the distance difference between the distance between each receiver receiving the wireless signal from the transmitter and the transmitter characterized by calculating a goodness of fit of the position value with each object constituting the cluster, there is an effect that the accurate positioning can be performed regardless of the shape or installation position of the receiver. ;
