다중 홉 무선 네트워크에서 전송된 신호는 일반적으로 여러 중계 터미널을 통해 전달됩니다. 따라서 중계 단말기의 페이딩 채널을 통한 재전송으로 인해 통신 품질이 저하됩니다. 기본적으로 CDD(Cyclic Delay Diversity) 기반의 기존 협력 중계 방식은 신호를 동시에 전송하는 수많은 중계 단말을 가질 수 있기 때문에 이러한 성능 저하를 줄입니다. 그러나 중계채널 환경을 고려하지 않고는 재전송으로 인해 최대의 다이버시티 이득을 얻을 수 없다. 본 논문에서는 이러한 성능 저하를 극복하기 위해 CRC(Cyclic Redundancy Check) 코드를 사용하는 CDD 기반 적응형 DF(Decode-and-Forward) 중계 방식을 제안한다. 시뮬레이션 결과는 제안한 방식이 다중 홉 네트워크에서 기존 방식보다 오류 성능이 더 향상되었음을 보여줍니다.

Abstract: In multi-hop wireless networks, the transmitted signal is generally forwarded over several relay terminals. So, the quality of communications is degraded due to these re-transmissions over fading channels in relay terminals. Basically, the conventional cooperative relaying scheme based on cyclic delay diversity (CDD) reduces this degradation because this scheme could have numerous relay terminals which simultaneously transmit the signals. However, we cannot obtain the maximum diversity gain because of the re-transmission without considering relay channel environments. In this letter, to overcome the decreased performance, we propose an adaptive decode-and-forward (DF) relaying scheme based on CDD which uses cyclic redundancy check (CRC) code. Simulation results show that the proposed scheme provides more improvement in error performance than the conventional schemes in multi-hop networks.

AB - In multi-hop wireless networks, the transmitted signal is generally forwarded over several relay terminals. So, the quality of communications is degraded due to these re-transmissions over fading channels in relay terminals. Basically, the conventional cooperative relaying scheme based on cyclic delay diversity (CDD) reduces this degradation because this scheme could have numerous relay terminals which simultaneously transmit the signals. However, we cannot obtain the maximum diversity gain because of the re-transmission without considering relay channel environments. In this letter, to overcome the decreased performance, we propose an adaptive decode-and-forward (DF) relaying scheme based on CDD which uses cyclic redundancy check (CRC) code. Simulation results show that the proposed scheme provides more improvement in error performance than the conventional schemes in multi-hop networks.
