Abstract
PURPOSE: To obtain the time difference of reference signals by receiving the radio waves from the respective transmitters individually at the receiving place and extracting the reference signal then measuring the time difference from the reference signal of the specific frequency extracted from the radio waves that can be received commonly.
CONSTITUTION: After the reference signal of the specific frequency is extracted from the radio wave W1 that can be received in common to the transmitter TXa, TXb side and receiving point R on the transmitter side, the reference signal is converted to the frequency in the transmission frequency band of the transmitters by using a frequency converting circuit MD and is transmitted individually from the transmitters TXa, TXb of different places by using the radio waves Wa, Wb of the same frequency. In the place R, the radio waves from the transmitters TXa, TXb are individually received and the reference signal is extracted, after which the time difference thereof with the reference signal of the specific frequency extracted from the radio wave W1 that can be received commonly is measured, whereby the time difference between the reference signals arriving at the place R through the transmitters of difference places may be obtained.
