본 논문에서는 더 높은 위성 용량을 얻기 위해 QPSK뿐만 아니라 16QAM 전송에도 적용 가능한 중첩 전송 위성 통신을 위한 간섭 제거기의 아키텍처를 제안합니다. FPGA 기반의 프로토타입으로 구현하여 성능을 검증합니다. 여기서는 0dB 이하와 같은 낮은 C/N 조건에서 작동할 수 있는 확장 정합 필터(EMF)를 사용하여 위성 왕복 지연을 측정하는 새로운 방법을 사용하는 것을 제안합니다. 이러한 성능을 고려하면 취소자는 순방향 링크와 역방향 링크의 전력 수준이 동일한 네트워크에서 작동할 수 있습니다. QPSK에 대한 실험실 테스트 결과, 약 30dB 정도 간섭을 억제할 수 있으며, 캔슬러로 인한 BER 저하가 작동하기에 충분히 작은 것으로 나타났습니다.

Abstract: This paper proposes an architecture of an interference canceller for satellite communications with super-posed transmission, which is applicable not only to QPSK but also to 16QAM transmission to get higher satellite capacity. We implement it as an FPGA-based prototype and verify its performance. We propose here to use a new method to measure the satellite round-trip delay using an extended matched filter (EMF), which can work in low C/N conditions such as 0 dB and under. Given this performance, our canceller can work in a network in which forward and reverse links have the same power level. The results of the laboratory tests for QPSK show that interference can be suppressed by about 30 dB and that the BER degradation due to the canceller was small enough for operation.
