PROBLEM TO BE SOLVED: To exclude an error due to interference by detecting the interference from other time division communication means to estimate transmission reception timing and matching its own transmission reception timing with the estimated transmission reception timing to establish synchronization with the other communication station. SOLUTION: There is a case that power of a leakage radio wave leaked from a radio wave sent from a monitor side 14 of a communication station 11 and reaching a monitor side 16 is more than the power of a radio wave sent from a side 15 to be monitored in a communication station 12 and reaching the monitor side 16. Thus, the leakage power acts like a disturbance radio wave on the monitor side 16 to cause interference. In order to prevent it, data transmission timing and reception timing of the communication station 12 is matched with transmission reception timing of the communication station 11. In order to match the transmission reception timing, the transmission timing and the reception timing of other system are estimated from a reception data error caused at the interference. The transmission reception timing of its own system is deviated to match it with the estimated transmission reception timing to establish synchronization. |
