Document Type and Number:
Japanese Patent JP2015080078
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a transmitting/receiving system including a plurality of transmitters and a receiver and capable of reducing demodulation (capture) load of a transmitted signal.SOLUTION: IMES100 includes a plurality of transmitters 10' and a receiver 20. Each of the plurality of transmitters 10' comprises a transmission unit 14 which transmits an IMES signal which can be demodulated by a GPS receiver, a reception unit 15 which receives the IMES signal transmitted from other transmitter 10' as a received signal, a demodulation unit 16 which demodulates the received signal, and a phase control unit 13 which determines a phase of the IMES signal transmitted by the transmission unit 14 according to a phase of the received signal demodulated by the demodulation unit 16. The receiver 20 comprises a reception unit 21 which receives the IMES signal transmitted from the transmitter 10' as a received signal and a demodulation unit 22 which demodulates the received signal by performing correlation operation between a replica signal and the received signal while shifting a phase of the replica signal.
