본 논문에서는 개별 중계 경로에 AM(Adaptive Modulation)을 적용한 AF(Amplify-and-Forward) 기반 양방향 중계망(TWRN)에서 채널 추정 오류가 미치는 영향을 분석합니다. 특히 Nakagami를 통해 채널 추정 오류로 인한 성능 저하를 조사합니다.m 페이딩 채널. 먼저 적응형 변조를 사용하는 AF 기반 TWRN(TWRN-AM)에 대한 채널 추정 오류가 있는 경우 종단 간 신호 대 잡음비(SNR), 누적 분포 함수 및 확률 밀도 함수를 도출합니다. . 도출된 SNR 통계를 활용하여 양방향 통신의 중단 이벤트 동안 전송이 발생하지 않는 중단 제약 조건을 사용하여 평균 스펙트럼 효율 및 비트 오류율의 정확한 표현을 제시합니다. 도출된 분석 결과를 바탕으로 시스템 중단을 최소화하여 평균 스펙트럼 효율을 향상시키는 TWRN-AM의 최적 전력 할당 방식을 제안합니다.

Abstract: In this paper, we analyze the impact of channel estimation errors in an amplify-and-forward (AF)-based two-way relaying network (TWRN) where adaptive modulation (AM) is employed in individual relaying path. In particular, the performance degradation caused by channel estimation error is investigated over Nakagami-m fading channels. We first derive an end-to-end signal-to-noise ratio (SNR), a cumulative distribution function, and a probability density function in the presence of channel estimation error for the AF-based TWRN with adaptive modulation (TWRN-AM). By utilizing the derived SNR statistics, we present accurate expressions of the average spectral efficiency and bit error rates with an outage-constraint in which transmission does not take place during outage events of bidirectional communications. Based on our derived analytical results, an optimal power allocation scheme for TWRN-AM is proposed to improve the average spectral efficiency by minimizing system outages.
