이하 첨부도면을 참조하여 본 고안의 실시예를 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
도2에 도시된 바와 같이, 송신할 데이터신호를 변조시키는데 필요한 발진신호를 공급하는 전압제어발진기(11)와 상기 발진신호를 이용하여 변조된 신호를 증폭시키는 전력증폭기(17)와, 상기 증폭신호를 대기중에 송출하는 안테나(13)를 구비한 송신부와; 상기 안테나(13)를 통해 수신하는 신호를 증폭하는 RF증폭기(12)와, 상기 전압제어발진기(11)를 공용하여 구성되며 다수의 수신채널을 제공하는 PLL신디사이저회로(10)와, 상기 PLL신디사이저회로(10)의 출력신호의 위상을 변환시키는 위상변환기(15)와, 상기 PLL신디사이저회로(10)의 출력과 상기 위상변환기(15)를 거친 출력을 사용하여 수신신호로부터 수신하고자 하는 데이터신호를 추출하는 직접변환복조기(14)를 구비한 수신부로 구성된다.As shown in Fig. 2, a voltage controlled oscillator 11 for supplying an oscillation signal for modulating a data signal to be transmitted, a power amplifier 17 for amplifying a signal modulated using the oscillation signal, and the amplification signal A transmission unit having an antenna 13 for transmitting the air in the air; An RF amplifier 12 for amplifying a signal received through the antenna 13, a PLL synthesizer circuit 10 configured to provide a plurality of reception channels in common by using the voltage controlled oscillator 11, and the PLL synthesizer The data signal to be received from the received signal is obtained by using the phase converter 15 for converting the phase of the output signal of the circuit 10 and the output of the PLL synthesizer circuit 10 and the output through the phase converter 15. It consists of a receiver having a direct conversion demodulator 14 for extracting.
상기와 같이 구성된 본 고안은 무선송수신장치에 데이터신호를 입력하면 전압제어발진기(11)의 발진신호를 이용하여 데이터신호를 변조하고 이를 다시 전력증폭기(17)에서 증폭한 후 안테나(13)를 통하여 대기중에 송출하고, 상기 안테나(13)를 통하여 상기 송출신호의 주파수와 동일주파수가 도입되면 RF증폭기(12)에서 증폭되어 PLL신디사이저회로(10)의 출력신호와 위상변환기(15)에서 상기 PLL신디사이저회로(10)의 출력위상을 변환시킨 신호와 상기 RF증폭기(12)의 출력을 직접변환복조기(14)에 입력하여 수신하고자 하는 데이터 신호를 추출한다.According to the present invention configured as described above, when the data signal is input to the wireless transceiver, the oscillation signal of the voltage controlled oscillator 11 is modulated and then amplified by the power amplifier 17 and then through the antenna 13. When transmitting in the air and the same frequency as the frequency of the transmission signal is introduced through the antenna 13, it is amplified by the RF amplifier 12, the output signal of the PLL synthesizer circuit 10 and the phase shifter 15 in the PLL synthesizer The output phase of the circuit 10 and the output of the RF amplifier 12 are input to the direct conversion demodulator 14 to extract a data signal to be received.
이때, 동일주파수대의 방해신호가 근접장소에서 사용되면 상기 방해신호 또한 안테나(13)를 통하여 도입된다. 그러나, PLL신디사이저회로(10)가 다수의 수신채널을 제공하기 때문에 동시에 수신된 동일주파수대의 데이터신호와 다른 방해신호는 서로 다른 채널로 수신하여 직접변환복조기(14)에 입력되므로 간섭효과가 나타나지 않는다. 따라서 직접변환복조기(14)에서는 서로 다른 두 입력신호중 사용자가 원하는 데이터신호만을 출력하게 된다.At this time, when the interference signal of the same frequency band is used in the vicinity, the interference signal is also introduced through the antenna 13. However, since the PLL synthesizer circuit 10 provides a plurality of reception channels, data signals and other interference signals of the same frequency band received at the same time are received on different channels and input to the direct conversion demodulator 14, so that no interference effect is exhibited. . Therefore, the direct conversion demodulator 14 outputs only data signals desired by the user among two different input signals.
본 고안에 의하면, 단신방식의 무선송수신 장치로부터 근접한 위치에서 동일 주파수대의 방해신호가 사용되더라도, 서로 다른 채널을 통해 신호를 수신하므로 방해신호와 간섭을 일으키지 않고 원하는 신호만을 검출해 낼 수 있다.According to the present invention, even if the interference signal of the same frequency band is used in a close position from the short-term radio transmission and reception apparatus, since the signal is received through different channels, only the desired signal can be detected without causing interference with the interference signal.
