The present invention relates to a wireless communication device for canceling cross polarization, and more particularly, by installing gain conversion and phase shifting amplifiers on the horizontal and vertical removal paths separately provided from the horizontal and vertical paths, respectively, the horizontal path and the vertical path. It relates to a wireless communication device for canceling cross polarization that can cancel cross polarization coming into a path.

단일 편파 송신 장치는 선형, 원형, 타원 편파 중 어느 하나인 단일 편파를 이용하여 단일 데이터(D, T)를 송신하고, 단일 편파 수신 장치는 단일 데이터(D, R)를 수신한다. 이를 단일 입력 단일 출력(SISO; Single-Input Single-Output) 방식이라고 한다. The single polarized wave transmitter transmits single data D and T using a single polarized wave that is any one of linear, circular, and elliptical polarization, and the single polarized wave receiver receives single data D and R. This is called a single-input single-output (SISO) method.

도 2를 참조하면, (a)는 이중 편파 송신 장치이고, (b)는 이중 편파 수신 장치이다. Referring to FIG. 2 , (a) is a double polarized wave transmitter, and (b) is a double polarized wave receiver.
이중 편파 송신 장치는 이중 편파를 이용하여 수평 데이터(D, T, H)와 수직 데이터(D, T, V)를 송신하고, 이중 편파 수신 장치는 수평 데이터(D, R, H)와 수직 데이터(D, R, V)를 수신한다. 이를 다중 입력 다중 출력(MIMO; Multi-Input Multi-Output) 방식이라고 한다.

이상적인 이중 편파 송수신 장치에서는 신호의 왜곡이나 간섭 없이 데이터가 송수신될 것이다. 그러나 일반적으로 수평(H) 편파 회로와 수직(V) 편파 회로 간의 커플링(coupling), 안테나의 수평 편파 포트와 수직 편파 포트 간의 커플링, 안테나 자체의 교차 편파 특성, 송신 장치와 수신 장치 간의 부정렬(misalignment), 안테나 표면의 거칠기(roughness)나 패키지(package)로 인한 크기 및 위상의 부정합(mismatch) 등으로 인해 신호의 왜곡이나 간섭이 발생하게 된다.

도 4는 본 발명에 의한 교차 편파 상쇄 회로의 구성을 나타낸 것이다.4 shows the configuration of a cross-polarization cancellation circuit according to the present invention.
이중편파 다중입력 다중출력 구조에서는 수신 신호에 균일하지 않은 크기와 위상을 가진 교차편파가 발생하는데, 도 4에 따른 교차 편파 상쇄 회로(100)를 이용해 수신 신호에 발생하는 교차 편파를 제거할 수 있다. In the dual polarization multiple input multiple output structure, cross polarization with non-uniform magnitude and phase is generated in the received signal, and cross polarization generated in the received signal can be removed by using the cross polarization canceling circuit 100 according to FIG. 4 . .
도 4를 참조하면, 기본적으로 수평경로 데이터(D, H 0)에는 교차편파로서 수직누설 데이터(D, V L0)가 발생하고, 수직경로 데이터(D, V 0)에는 교차편파로서 수평누설 데이터(D, H L0)가 발생한다. Referring to FIG. 4 , vertical leakage data (D, V L0 ) is basically generated as a cross-polarized wave in the horizontal path data (D, H 0 ), and horizontal leakage data as a cross-polarized wave in the vertical path data (D, V 0 ) is basically generated. (D, H L0 ) occurs.
수평경로 데이터(D, H 0)에 교차편파로서 수직누설 데이터(D, V L0)가 혼합된 데이터를 수평경로 혼합 데이터(D, H 0 + D, V L0)라고 하고, 수직경로 데이터(D, V 0)에 교차편파로서 수평누설 데이터(D, H L0)가 혼합된 데이터를 수직경로 혼합 데이터(D, V 0 + D, H L0)라고 한다. The data in which the vertical leakage data (D, V L0 ) is mixed with the horizontal path data (D, H 0 ) as a cross polarization is called the horizontal path mixed data (D, H 0 + D, V L0 ), and the vertical path data (D , V 0 ) and horizontal leakage data (D, H L0 ) as a cross-polarized wave is called vertical path mixed data (D, V 0 + D, H L0 ).
수평경로(1)는 수평경로 데이터가 통과하는 경로로서 이득변환 증폭기(102) 및 위상 천이기(112)가 배치되어 있다. 본 발명의 실시예에서는 수평 편파 데이터가 처리되는 수평경로를 하나의 예로 나타내고 있는데, 이중편파 구조에서 다양한 편파(원형, 타원형 편파)가 사용될 수 있으므로 수평경로(1)는 제1편파 데이터가 통과하는 제1경로가 될 수 있다. The horizontal path 1 is a path through which the horizontal path data passes, and the gain conversion amplifier 102 and the phase shifter 112 are disposed. In the embodiment of the present invention, a horizontal path through which horizontally polarized data is processed is shown as an example. Since various polarizations (circular and elliptical polarizations) can be used in the double polarization structure, the horizontal path 1 is the first polarization path through which the first polarization data passes. It can be the first route.
수직경로(2)는 수직경로 데이터가 통과하는 경로로서 이득변환 증폭기(103) 및 위상 천이기(113)가 배치되어 있다. 마찬가지로 본 발명의 실시예에서는 수직 편파 데이터가 처리되는 수직경로를 하나의 예로 나타내고 있는데, 이중편파 구조에서 다양한 편파(원형, 타원형 편파)가 사용될 수 있으므로 수직경로(2)는 제2편파 데이터가 통과하는 제2경로가 될 수 있다. The vertical path 2 is a path through which the vertical path data passes, and the gain conversion amplifier 103 and the phase shifter 113 are disposed. Similarly, in the embodiment of the present invention, a vertical path through which vertical polarization data is processed is shown as an example. Since various polarizations (circular and elliptical polarization) can be used in the dual polarization structure, the vertical path 2 passes through the second polarization data. It can be a second route to
수직경로(2)의 이득변환 증폭기(103)의 입력 단과 수평경로(1)의 위상 천이기(111)의 출력 단을 연결한 수직 제거경로(3) 상에는 이득변환 증폭기(101) 및 위상 천이기(111)가 배치되어 있다. A gain conversion amplifier 101 and a phase shifter on the vertical removal path 3 connecting the input terminal of the gain conversion amplifier 103 of the vertical path 2 and the output terminal of the phase shifter 111 of the horizontal path 1 (111) is arranged.
또한, 수평경로(1)의 이득변환 증폭기(102)의 입력 단과 수직경로(2)의 위상 천이기(1141) 출력 단을 연결한 수평 제거경로(4) 상에는 이득변환 증폭기(104) 및 위상 천이기(114)가 배치되어 있다. In addition, on the horizontal removal path 4 connecting the input terminal of the gain conversion amplifier 102 of the horizontal path 1 and the phase shifter 1141 output terminal of the vertical path 2, the gain conversion amplifier 104 and the phase shift A gear 114 is disposed.
수직 제거경로(3)와 수평 제거경로(4)는 이중편파 구조에서 선형 편파를 사용한 경우, 수평경로 데이터에 발생하는 수직경로 누설 데이터와 수직경로 데이터에 발생하는 수평경로 누설 데이터를 제거하기 위한 경로로서, 다른 편파가 사용될 수 있으므로, 수직 제거경로(3)는 제2편파 데이터에 발생하는 교차편파 데이터(누설 데이터)를 제거하기 위한 제3경로가 되고, 수평 제거경로(4)는 제1편파 데이터에 발생하는 교차편파 데이터를 제거하기 위한 제4경로가 될 수 있다. The vertical removal path (3) and the horizontal removal path (4) are paths for removing the vertical path leakage data generated in the horizontal path data and the horizontal path leakage data generated in the vertical path data when linear polarization is used in the dual polarization structure. , since other polarizations can be used, the vertical removal path 3 becomes a third path for removing cross-polarization data (leakage data) generated in the second polarization data, and the horizontal removal path 4 serves as the first polarization data. It may be a fourth path for removing cross-polarization data generated in the data.
본 발명의 실시예에서는 제1경로 내지 제4경로 상에 이득변환 증폭기 및 위상 천이기를 각각 배치하고 있는데, 제1경로 및 제2경로 상에는 일반적인 증폭기를 사용할 수 있고, 위상 천이기를 생략할 수 있다. In the embodiment of the present invention, a gain conversion amplifier and a phase shifter are respectively disposed on the first to fourth paths, but a general amplifier may be used on the first and second paths, and the phase shifter may be omitted.

The horizontal path mixed data (D, H 0 + D, V L0 ) is gain-converted and phase-shifted through the gain conversion amplifier 102 and the phase shifter 112 in the horizontal path 1, and the vertical path mixed data D , V 0 + D, H L0 ) is the horizontal leakage data (D, H L0 ) is removed through the gain conversion amplifier 101 and the phase shifter 111 in the vertical removal path (3), the vertical path data (D , V 0 ) is gain-converted and phase-shifted so that the vertical leakage data (D, V L0 ) passed through the horizontal path 1 have the same magnitude and opposite phase.

In this way, the horizontal path mixed data (D, H 0 + D, V L0 ) passed through the horizontal path (1) and the vertical path mixed data (D, V 0 + D, H L0 ) passed through the vertical removal path (3) are horizontal By summing at the output stage 5 of the path 1, the vertical leakage data (D, V L0 ) is removed, so that only the horizontal path data (D, H 0 ) without cross polarization comes out.

Similarly, the vertical path mixed data (D, V 0 + D, H L0 ) is gain-converted and phase-shifted through the gain conversion amplifier 103 and the phase shifter 113 in the vertical path 2, and the horizontal path mixed data (D, H 0 + D, V L0 ) is the vertical leakage data (D, V L0 ) is removed through the gain conversion amplifier 104 and the phase shifter 114 in the horizontal removal path (4), the horizontal path data Gain conversion and phase shift are performed so that (D, H 0 ) has the same magnitude as the horizontal leakage data (D, H L0 ) passing through the vertical path (2) and has the opposite phase.
이와 같이 수직경로(2)를 거친 수직경로 혼합 데이터(D, V 0 + D, H L0)와 수평 제거경로(4)를 거친 수평경로 혼합 데이터(D, H 0 + D, V L0)가 출력 단(6)에서 합해짐으로써 수평누설 데이터(D, H L0)가 제거되어 교차 편파가 없는 수직경로 데이터(D, V 0)만 나오게 된다. In this way, the mixed vertical path data (D, V 0 + D, H L0 ) through the vertical path (2) and the horizontal path mixed data (D, H 0 + D, V L0 ) through the horizontal removal path (4) are output. By summing in stage (6), the horizontal leakage data (D, H L0 ) is removed, and only the vertical path data (D, V 0 ) without cross polarization comes out.
