본 논문에서는 양방향 직교 변조 시스템의 프레임 동기화 방법을 설명합니다. 이중 직교 변조 시스템에서는 여러 개의 이중 직교 시퀀스가 데이터 전송에 사용됩니다. 전송된 시퀀스가 프레임마다 변경될 수 있기 때문에 양방향 직교 변조 시스템의 프레임 동기화는 어렵습니다. 제안된 방법에서 각 bi-orthogonal 시퀀스는 두 개의 서로 다른 내부 시퀀스로 구성된다. 각 이중 직교 시퀀스는 두 개의 서로 다른 내부 시퀀스의 동일한 배열을 갖습니다. 수신기는 내부 시퀀스의 배열을 관찰하여 프레임 타이밍을 추적할 수 있습니다. 본 논문에서는 우리의 방법을 기반으로 개발한 시스템의 추적 성능을 고려한 비트 오류율 성능을 분석한다. 코드 분할 다중 접속(CDMA) 시스템에서 제안된 시스템의 스펙트럼 효율성도 조사됩니다. 그 결과 제안한 시스템이 동기식 CDMA 시스템에서 효과적임을 확인하였다.

Abstract: In this paper, we describe a frame synchronization method for bi-orthogonal modulation systems. In bi-orthogonal modulation systems, several bi-orthogonal sequences are used for data transmission. Frame synchronization in bi-orthogonal modulation systems is difficult because transmitted sequences can change every frame. In the proposed method, each bi-orthogonal sequence consists of two different inner sequences. Each bi-orthogonal sequence has the same arrangement of two different inner sequences. A receiver can track the frame timing by observing the arrangement of inner sequences. In this paper, we analyze the bit error rate performance that takes into account the tracking performance of a system we developed based on our method. The spectral efficiency of the proposed system in code division multiple access (CDMA) systems is also investigated. As a result, we found that the proposed system is effective in synchronous CDMA systems.
