본 논문에서는 무선 전이중 중계 시스템에서 아날로그 회로 영역의 잔여 자기간섭을 크게 줄이는 방안을 제안한다. 전이중 릴레이 시스템은 스펙트럼 효율을 개선하기 위해 릴레이 노드에서 전송 및 수신을 위해 동일한 시간 및 주파수 리소스를 활용합니다. 제안하는 방식은 중계기에서 송신기의 메인 빔 방향을 변경한 후 잔류 자기 간섭을 최소화하는 최적의 방향을 선택하여 피드백 경로의 다중 응답을 측정합니다. 최적의 방향을 선택하기 위한 기준으로 분석적 잔여 자기간섭을 도출하였다. 또한 본 논문에서는 아날로그 회로 도메인에서 다이나믹 레인지에 의존하는 ADC(analog-to-digital converter) 이전에 잔류 자기 간섭 전력의 대상을 고려한다. 잔류 간섭이 목표를 초과하는 분석적 확률은 피드백 경로의 측정된 응답 수를 결정하는 데 도움이 되도록 유도됩니다. 컴퓨터 시뮬레이션은 분석 결과를 검증하고, 특히 6개의 후보로 제안된 방식이 피드백 경로를 레일리 페이딩으로 모델링한 기존 방식과 비교하여 잔류 자기 간섭이 목표 전력을 초과할 확률 0.01에서 약 XNUMXdB까지 잔류 자기 간섭을 개선함을 보여줍니다.

Abstract: This paper proposes a scheme that reduces residual self-interference significantly in the analog-circuit domain on wireless full-duplex relay systems. Full-duplex relay systems utilize the same time and frequency resources for transmission and reception at the relay node to improve spectral efficiency. Our proposed scheme measures multiple responses of the feedback path by changing the direction of the main beam of the transmitter at the relay, and then selecting the optimal direction that minimizes the residual self-interference. Analytical residual self-interference is derived as the criterion to select the optimal direction. In addition, this paper considers the target of residual self-interference power before the analog-to-digital converter (ADC) dependent on the dynamic range in the analog-circuit domain. Analytical probability that the residual interference exceeds the target is derived to help in determining the number of measured responses of the feedback path. Computer simulations validate the analytical results, and show that in particular, the proposed scheme with ten candidates improves the residual self-interference by approximately 6dB at the probability of 0.01 that the residual self-interference exceeds target power compared with a conventional scheme with the feedback path modeled as Rayleigh fading.
