초록

본 논문에서는 동일 대역에서 동시에 전 이중 통신을 하기 위한 프레임 구조를 사용하는 터보 등화기를 결합한 SSD (Simultaneous Single band Duplex) 시스템을 제안한다. 본 논문에서는 자기 간섭 신호를 보다 효율적으로 제거하기 위하여 프레임 구조를 사용한다. 본 논문에서는 송수신 프레임 구조를 사용할 경우의 시스템의 특성을 분석하기 위하여 프레임 구조를 사용하지 않는 시스템과 성능을 비교하였다. 시뮬레이션 결과로 본 논문에서 제안하는 시스템은 프레임 구조를 사용하였을 경우, 프레임 구조를 사용하지 않았을 경우보다 더 좋은 성능을 내며, 프레임 구조를 사용하는 제안하는 시스템은 더 적은 터보 등화기의 전역 반복으로 프레임 구조를 사용하지 않은 시스템과 유사한 성능을 낼 수 있는 것을 확인하였다.

In this paper, we propose a SSD(Simultaneous Single band Duplex) system using turbo equalizer with frame structure for simultaneous full-duplex communication in single band. the proposed system uses frame structure for self-interference cancellation effectively. In this paper, performance of the proposed system with frame structure compares to performance of SSD system without frame structure to analysis performance of the proposed system with frame structure. Simulation results show that the performance of proposed system with frame structure is batter than performance of SSD system without frame structure when the number of global iterations of both system is same. Using proposed system with frame structure, we can verify that the performance like SSD system without frame structure by few global iteration of turbo equalizer.
