본 논문에서는 비협조적인 하향링크 다중셀 동일채널간섭(CCI) 환경에서 최대 우도 검출기(MLD)의 BER 상한을 최소화할 수 있는 MIMO-OFDM 프리코더를 제안한다. 기지국(BS) 간 협력이 없으므로 간섭에 대한 정보를 이동국(MS)에서 추정한 후 프리코더를 위해 원하는 기지국으로 피드백할 수 있다고 가정한다. 제안된 방식은 CCI + 잡음에 대해 평균화된 PEP(Pairwise Error Probability)로부터 도출된 BER 상한을 최소화하기 위해 전송 전력 제약 하에서 프리코딩 매개변수를 제어합니다. 컴퓨터 시뮬레이션은 제안된 프리코더가 셀 경계 사용자의 BER 성능을 효과적으로 향상시킬 수 있으며 채널 용량을 최대화하고 MSE를 최소화하는 것을 목표로 하는 고유 모드 및 MMSE(최소 평균 제곱 오류) 프리코딩 전송에 비해 BER 측면에서 우수함을 보여줍니다. .

Abstract: This paper proposes a MIMO-OFDM precoder that can minimize a BER upper bound of the maximum likelihood detector (MLD) under a non-cooperative downlink multicell co-channel interference (CCI) environment. Since there is no cooperation among base stations (BSs), it is assumed that information on the interference can be estimated at a mobile station (MS) and then fed back to the desired BS for the precoder. The proposed scheme controls its precoding parameters under a transmit power constraint so as to minimize the BER upper bound, which is derived from the pairwise error probability (PEP) averaged with respect to CCI plus noise. Computer simulations demonstrate that the proposed precoder can effectively improve BER performance of cell edge users and is superior in terms of BER to the eigenmode and the minimum mean squared error (MMSE) precoded transmissions which aim to maximize the channel capacity and to minimize MSE, respectively.
