Alamouti의 OSTBC(직교 시공간 블록 코드)는 페이딩 채널 효과를 완화하기 위해 전송 다양성을 활용하는 간단하면서도 중요한 기술입니다. 본 논문에서는 Alamouti의 OSTBC의 비트 오류율(BER) 성능에 시간 선택형 채널과 채널 추정 오류가 미치는 영향을 분석합니다. 우리는 실제 채널 대신 최소 평균 제곱 오류(MMSE) 채널 추정치를 사용하여 선형 디코딩에 대한 BER 성능의 분석적 표현을 개발합니다. 표현식을 기반으로 칼만 필터링으로 채널을 추적하는 의사결정 모드에서 BER 성능 한계를 도출합니다. 분석을 검증하고 시간 선택 페이딩 및 채널 추정 오류가 BER 성능에 미치는 영향을 확인하기 위해 수치 예제가 제공됩니다.

Abstract: Alamouti's orthogonal space-time block code (OSTBC) is a simple yet important technique to take advantage of transmit diversity to mitigate fading channel effects. In this paper, we analyze the effects of time-selective channels and channel estimation errors on the bit error rate (BER) performance of Alamouti's OSTBC. We develop an analytical expression of the BER performance for the linear decoding with minimum mean squared error (MMSE) channel estimates in place of the true channel. Based on the expression, we derive a BER performance limit in decision-directed mode where the channel is tracked with Kalman filtering. Numerical examples are provided to validate our analysis and to see the impact of time-selective fading and channel estimation errors on the BER performance.
