본 논문에서는 위성/지상 통합 시스템에서 효율적으로 동작할 수 있는 공간 다중화 다중 안테나 방식을 위한 효율적인 인터리빙기법을 제안한다. 제안된 인터리빙 방식에서는 위성 경로로 전송되는 비트들에 대하여 효과적으로 인터리빙을 적용함으로써, 수신부호어에서 이웃하는 매 비트마다 서로 다른 채널 이득을 가질 수 있도록 한다. 이와 같은 인터리빙 방식을 적용하면 위성 경로에서의 긴 상관시간으로 인한 성능 저하를 효과적으로 보상할 수 있다. 또한, 제안된 인터리빙 방식은 하드웨어 복잡도 측면에서 효율적으로 구현이 가능하며, 시간 지연도 최소화 할 수 있다.
