<P>PROBLEM TO BE SOLVED: To provide a broadcast wave signal retransmission system that requires no radio license, imposes no restriction on the arrangement or the shape of devices, and requires no change in frequency. <P>SOLUTION: The retransmission system includes a transmission unit 4 and a reception unit 8. The transmission unit 4 includes a plurality of retransmission antennas 7 and a transmitting-side device 5 for distributing a given broadcast wave signal into a plurality of signals, giving phase amounts different from each other to the plurality of distributed broadcast wave signals based on a given reference signal and supplying the plurality of broadcast wave signals, to which the different phase amounts have been given, respectively, to the plurality of retransmission antennas. The reception unit 8 includes a reception antenna 9 for receiving a plurality of broadcast waves retransmitted from the plurality of retransmission antennas 7 in the transmission unit 4, and an oscillator 20 for oscillating the reference signal to be transmitted from the reception antenna to the transmission unit. <P>COPYRIGHT: (C)2010,JPO&INPIT |
