최근에는 GI 삽입이 필요 없는 중첩 FDE라고 하는 새로운 주파수 영역 등화(FDE) 기술이 제안되었습니다. 그러나 잔여 IBI(Inter/Intra-Block Interference)는 완전히 제거할 수 없습니다. 이에 더해, DS-CDMA(Multicode Direct Sequence Code Division Multiple Access)의 경우 FDE 이후 잔여 ICI(Inter-Chip Interference)가 존재하면 확산 코드 간의 직교성이 왜곡됩니다. 본 논문에서는 잔여 IBI와 잔여 ICI를 모두 억제하기 위해 멀티코드 DS-CDMA에 대한 반복적 중첩 FDE를 제안합니다. 반복적 중첩 FDE에서는 MMSE(Joint Minimise Mean Square Error)-FDE와 ICI 제거가 충분한 횟수만큼 반복됩니다. 반복 오버랩 FDE를 사용한 비트 오류율(BER) 성능은 컴퓨터 시뮬레이션을 통해 평가됩니다.

Abstract: Recently, a new frequency-domain equalization (FDE) technique, called overlap FDE, that requires no GI insertion was proposed. However, the residual inter/intra-block interference (IBI) cannot completely be removed. In addition to this, for multicode direct sequence code division multiple access (DS-CDMA), the presence of residual inter-chip interference (ICI) after FDE distorts orthogonality among the spreading codes. In this paper, we propose an iterative overlap FDE for multicode DS-CDMA to suppress both the residual IBI and the residual ICI. In the iterative overlap FDE, joint minimum mean square error (MMSE)-FDE and ICI cancellation is repeated a sufficient number of times. The bit error rate (BER) performance with the iterative overlap FDE is evaluated by computer simulation.

AB - Recently, a new frequency-domain equalization (FDE) technique, called overlap FDE, that requires no GI insertion was proposed. However, the residual inter/intra-block interference (IBI) cannot completely be removed. In addition to this, for multicode direct sequence code division multiple access (DS-CDMA), the presence of residual inter-chip interference (ICI) after FDE distorts orthogonality among the spreading codes. In this paper, we propose an iterative overlap FDE for multicode DS-CDMA to suppress both the residual IBI and the residual ICI. In the iterative overlap FDE, joint minimum mean square error (MMSE)-FDE and ICI cancellation is repeated a sufficient number of times. The bit error rate (BER) performance with the iterative overlap FDE is evaluated by computer simulation.
