이동통신 기지국 또는 MBTS(17)에 송수신 되는 변복조된(아날로그 또는 디지털, CDMA, 등) 고주파 신호(송신, 수신)를 광에너지로 변환하여 저손실 광케이블로 원거리 전송하여 다시 고주파 신호로 변환하여 고주파 고출력으로 증폭하여 음영지역 서비스하는 장치로 순방향 통신은 기지국에서 음영지역전송으로 기지국 또는 MBTS(17)에서 송출한 변조된 고주파 신호가 고주파광변환기(1) 변환하여 f1(예, 1.5㎛파장) 광다이프렉서를 통하여 과케이블(18)를 음영지역으로 전송한다. 음영지역에 있는 광중계기에 광다이프렉서(4)를 통하여 광고주파 변환기(5)에서 고주파로 변환증폭하고 다시 고주파 고출력 증폭기(7)로 증폭하여 고주파 다이프렉서(8)를 통하여 송수신 안테나(18)에 연결하여 전파 복사하여 가입자 단말기에 전파도달하여 수신하게 된다. 또 역방향 단말기에서 송신한 전파는 안테나1(18)과 안테나2(19)로 이격하여 수신하여 공간다이버시티를 형성하고 안테나1(18)에 수신된 전파는 다이프렉서(8)를 통하여 저잡음 증폭기(9)에서 증폭하여 수신 다이프렉서에 인입된다. 또 동일 단말기 송신신호는 안테나2(19)에도 수신되어 저잡음 증폭기(10)으로 증폭하고 주파수변환기(11)에서 고주파 발진기(12)에서 발생하는 전파와 합성하여 단말기에서 송신한 전파와는 전혀다른 전파를 생성한다. 이렇게하여 다이프렉서(13)에 인입한다. 즉 다이프렉서(13)은 안테나1(18)에서 인입한 수신전파와 안테나2(19)에서 수신 변환된 전파 2종류가 인입하여 1개에 출력에 2개 다른 수신 주파수가 출력된다. 2개 주파수는 다시 고주파 광변환기(6)에 인입한다. 2개의 고주파는 고주파광변환기(6)에서 광에너지 f2(예 1.3㎛파장)인 f1과 전펴다른 광으로 변환된다. f2는 광다이프렉서(4)에서 연결하여 광에너지f1에 간섭하지 않고 동일한 광케이블(20)을 통하여 역(ㄱ)으로 전송한다.Modulated and demodulated (analog or digital, CDMA, etc.) high frequency signals (transmitting and receiving) transmitted to and received from the mobile communication base station or MBTS 17 are converted to optical energy, and are transmitted to a long distance with a low loss optical cable, and then converted into high frequency signals to high frequency high output. Amplified and shaded area service forward communication is a modulated high frequency signal transmitted from the base station or MBTS (17) from the base station to the shadow area transmission by converting the high frequency optical converter (1) f 1 (eg 1.5㎛ wavelength) The over cable 18 is routed through the lexer to the shaded area. The optical repeater in the shaded region converts and amplifies the radio frequency converter 5 into a high frequency through an optical diplexer 4 and amplifies the high frequency high output amplifier 7 to transmit and receive antennas 18 through a high frequency diplexer 8. ) To receive the radio wave by copying the radio wave to the subscriber station. In addition, the radio wave transmitted from the reverse terminal is separated by antenna 1 (18) and antenna 2 (19) to form a spatial diversity, and the radio wave received by antenna 1 (18) is a low noise amplifier through the diplexer (8). It is amplified in (9) and introduced into the receiving diplexer. The same terminal transmission signal is also received by the antenna 2 (19), amplified by the low noise amplifier 10, and a radio wave that is completely different from the radio wave transmitted from the terminal by combining with the radio wave generated by the high frequency oscillator 12 in the frequency converter 11 Create In this way, it enters into the diplexer 13. That is, the diplexer 13 receives two kinds of radio waves received by the antenna 1 18 and radio waves received and converted by the antenna 2 19, and outputs two different reception frequencies to one output. The two frequencies enter the high frequency light converter 6 again. The two high frequencies are converted to light different from f 1 , which is light energy f 2 (eg, 1.3 μm wavelength), in the high frequency light converter 6. f 2 is connected by the optical diplexer 4 and transmitted to the reverse a through the same optical cable 20 without interfering with the optical energy f 1 .

(ㄱ)전송된 f2광다이플렉서(3)를 통하여 f1광에너지에 간섭하지않고 광 고주파변환기(2)에 인입된다. 이에 인입된 광은 음영지역에서 송출한 고주파안테나1(18) 인입된 주파수와 안테나2(19)에 인입 변환된 주파수를 재생한다. 이 2개 주파수는 다이프렉서(14)에 인입되어 2개 출력주파수 안테나1(18)에 수신된 주파수와 안테나2(19)에 수신된 주파수변환 된 것 각각 따로따로 출력한다. 안테나1(18)에 수신된 주파수는 직접 기지국 수신기로 전송하고 안테나2(19)에 수신 변환된 주파수는 다시 주파수 변환기(15)에 인입되서 국부발진 주파수(16)에서 출력하는 주파수와 합쳐 안테나2(19)에서 수신한 주파수와 매우 같은 주파수를 재생한다. 국부발지기(16)에서 발진하는 주파수는 안테나1(18)에서 인입한 주파수와 같은 신호가 되도록 동기기(21)에서 동기 콘트롤한다. 변환 재생한 주파수변환기(15)의 출력 고주파는 주파수를 안테나1(18)에서 수신된 주파수와 똑 같은 신호를 출력 레벨만 다르게 된다. 이 신호를 기지국(17)의 수신기에 인입하여 공간다이버시티 동작하게 한다.(A) Through the transmitted f 2 optical diplexer 3 is introduced into the optical high frequency converter 2 without interfering with the f 1 optical energy. The incoming light reproduces the frequency introduced by the high frequency antenna 1 (18) transmitted from the shaded region and the frequency converted into the antenna 2 (19). These two frequencies are introduced into the diplexer 14 and output separately from the frequencies received by the two output frequencies antenna 1 18 and the frequency transformed received by the antenna 2 19. The frequency received by the antenna 1 (18) is transmitted directly to the base station receiver, and the frequency converted and received by the antenna 2 (19) is introduced into the frequency converter 15 and combined with the frequency output from the local oscillation frequency (16). Play a frequency very similar to the frequency received in (19). The frequency oscillated by the local oscillator 16 is synchronously controlled by the synchronizer 21 so as to be the same signal as the frequency introduced by the antenna 1 18. The output high frequency of the converted frequency converter 15 is the same frequency as the frequency received from the antenna 1 (18), only the output level is different. This signal is introduced into the receiver of the base station 17 to allow spatial diversity operation.

종래의 것은 이와 같이 하지않고 광케이블을 2회선 사용하였다. 본 발명은 이를 달리하여 단일선으로 전송하도록 설계되어 경비가 1/2 절감하는 효과가 있다.The conventional cable used two wires without doing this. The present invention is designed to transmit to a single line by different from this has the effect of reducing the cost 1/2.

본 발명 다이버시티형 이동통신 광 중계장치는 전술한 실시예에 국한되지 않고 본 발명의 기술 사상이 허용하는 범위 내에서 다양하게 변형하여 실시할 수가 있다.The diversity mobile communication optical relay device of the present invention is not limited to the above-described embodiment, and can be modified in various ways within the scope of the technical idea of the present invention.
