Abstract

디지탈 통신단말장치에서 해당 모델의 모든 기기에 동일한 송수신지연시간을 일괄적으로 적용할 경우 기기별 편차가 무시됨에 따라 송수신시 동기 오차가 발생하는 것을 개선한다. 이를 위하여 송신부를 통해 미리 설정된 시험신호를 송신하고 송신한 시험신호를 복조장치를 통해 수신하는 것에 의해 송신부에서 발생하는 송신지연시간을 측정하고, 신호발생장치를 통해 시험신호를 송신하고 송신한 시험신호를 수신부를 통해 수신하는 것에 의해 수신부에서 발생하는 수신지연시간을 측정한다. 이후 송신모드로 동작시에 송신지연시간과 수신지연시간을 더한 고유지연시간만큼 미리 송신데이타를 송신부에 인가한다. 따라서 각 통신 단말장치마다 서로 다른 송수신지연특성에 대하여 적응적으로 송수신지연시간을 정확하게 보정할 수 있게 된다.When the same communication delay time is applied to all devices of the corresponding model in the digital communication terminal device, the error of transmission and reception is improved as the deviation of each device is ignored. To this end, by transmitting a test signal set in advance through the transmitter and receiving the transmitted test signal through a demodulator, the transmission delay time generated by the transmitter is measured, and the test signal is transmitted and transmitted through the signal generator. The reception delay time generated at the reception unit is measured by receiving the signal through the reception unit. Thereafter, when operating in the transmission mode, the transmission data is applied to the transmitter in advance by the inherent delay time plus the transmission delay time and the reception delay time. Therefore, it is possible to accurately correct the transmission / reception delay time for each transmission / reception delay characteristic for each communication terminal device.
