OFDM 기반 FDR(Full Duplex Relay)의 DF(Decode and Forward) 방식에서는 피드백 간섭 제거에 있어서 주파수 영역 접근 방식이 시간 영역 접근 방식보다 더 효율적이다. 그러나 피드백 간섭 신호와 기지국(BS)에서 원하는 신호 사이의 타이밍 불일치로 인해 ISI(Inter-Symbol Interference) 및 ICI(Inter-Carrier Interference)가 발생할 수 있습니다. 이 편지에서는 동기식 유형과 비동기식 OFDM 기반 FDR에 대한 타이밍 불일치의 영향을 업링크 및 다운링크 사례에서 조사합니다. 주파수 영역 피드백 간섭 제거기를 사용하여 OFDM 기반 FDR에서 ISI 및 ICI를 최소화하기 위한 동기화 절차 및 기술을 제안합니다.

Abstract: In a Decode and Forward (DF) type of an OFDM-based Full Duplex Relay (FDR), the frequency-domain approach is more efficient than the time-domain approach for feedback interference cancellation. However, Inter-Symbol Interference (ISI) and Inter-Carrier Interference (ICI) may occur due to timing mismatch between the feedback interference signal and the desired signal from the Base Station (BS). In this letter, the effects of a timing mismatch on synchronous types and asynchronous types of OFDM-based FDRs are investigated in uplink and downlink cases. A synchronization procedure and techniques for minimizing ISI and ICI in OFDM-based FDRs with a frequency-domain feedback interference canceller are proposed.

AB - In a Decode and Forward (DF) type of an OFDM-based Full Duplex Relay (FDR), the frequency-domain approach is more efficient than the time-domain approach for feedback interference cancellation. However, Inter-Symbol Interference (ISI) and Inter-Carrier Interference (ICI) may occur due to timing mismatch between the feedback interference signal and the desired signal from the Base Station (BS). In this letter, the effects of a timing mismatch on synchronous types and asynchronous types of OFDM-based FDRs are investigated in uplink and downlink cases. A synchronization procedure and techniques for minimizing ISI and ICI in OFDM-based FDRs with a frequency-domain feedback interference canceller are proposed.
