이 편지에서는 서로 다른 임의 반송파 주파수 오프셋에 의해 교란되는 주파수 선택 페이딩 채널을 통한 릴레이 지원 전송 시나리오가 고려됩니다. OFDM 및 BDD(블록 이중 차동) 설계는 ISI(기호간 간섭) 및 CFO(반송파 주파수 오프셋) 문제를 극복하기 위해 구현되었습니다. 우리는 주파수 선택 페이딩 채널을 통한 무선 협력 통신에서 BDD 설계를 사용한 디코딩 및 전달 중계의 기호 오류율(SER) 성능을 분석하고 중계 시 평균 SER에 대한 이론적 상한을 도출합니다.R)에는 오류가 없습니다. 우리의 분석에서 시스템 성능은 다음의 능력에 의해 영향을 받는다는 것을 알 수 있습니다. R 디코딩할 때, 그리고 언제 R 오류 없이 디코딩하면 수신기에서 채널 상태 정보와 CFO 정보에 대한 지식이 필요 없이 공간 및 다중 경로 다양성을 얻을 수 있습니다. 우리의 이론적 분석을 확증하기 위해 수치적 예가 제공됩니다.

Abstract: In this letter, a relay-assisted transmission scenario over frequency-selective fading channels perturbed by different random carrier frequency offsets is considered. OFDM and block-double differential (BDD) design are implemented to overcome the problem of intersymbol interference (ISI) and carrier frequency offsets (CFOs). We analyze the symbol error rate (SER) performance of decode-and-forward relaying with BDD design in wireless cooperative communications over frequency-selective fading channels and derive a theoretical upper bound for average SER when the relay (R) is error free. It can be seen from our analysis that the system performance is influenced by the ability of R to decode, and when R decodes without error, both spatial and multipath diversity can be obtained without requiring any knowledge of channel state information and CFO information at the receivers. Numerical examples are provided to corroborate our theoretical analysis.
