TIME SYNCHRONIZATION AND INTERFERENCE CANCELLATION METHOD OF GROUND FIXED TRANSMITTER FOR RADIO POSITIONING

摘要

PURPOSE: The time synchronization of a ground fixed transmitter for radio wave positioning and a method for canceling interference are provided to minimize times to receive a signal in which a receiver is necessary since a plurality of transmitters simultaneously transmits the signal without the interference of the transmitter. CONSTITUTION: A secondary transmitter measures a first time error by respectively receiving the signal of a primary transmitter and a signal of the other secondary transmitter which adjusts synchronization for the primary transmitter(S110). The secondary transmitter measures a second time error by respectively receiving the signal of the primary transmitter and a signal from the secondary transmitter itself(S120). The secondary transmitter transmits the first time error and the second time error to other secondary transmitters(S130).
