Abstract

PURPOSE: To eliminate the effect caused by the uneven delay phase amount between the transmitter and the receiver of the repeater station by giving the preliminary adjustment of the delay phase amount between the master station and the slave station in the method with which the data signal delay phase amount is made constant between the base stations by means of the radio system.
CONSTITUTION: Master station 20 contains 1st transmitter and receiver 2 and 3 of the radio system plus phase difference measurement unit 1 connected to 1st and 2nd variable delay circuit 4 and 12; 2nd slave station 21 includes 2nd transmitter and receiver 10 and 11, demodulator 8 and 2nd transmitter 9; and 1st slave station 22 contains demodulator 16 plus 3rd transmitter 17 and 18 respectively. A connection is given betwen 2 and 11 as well as between 3 and 10 via the wired circuit, and the radio wave is repeated between station 20 and 22 via station 21. In such system, the delay phase amount is measured by unit 1 during the time the wave transmitted from transmitter 2 is received at receiver 3. And the delay phase amount is adjusted via delay circuit 5 and 13 and then applied to demodulator 8 and 16 of station 21 and 22 via the wire to perform an adjustment of the phase amount.
