초록

본 논문에서는 PCS환경에서 다중 사용자 간섭의 제거를 위한 직렬 간섭 제거 방식을 분석하고, 이를 개선한 새로운 직렬 간섭 제거 방식을 제안한다. DS/CDMA 통신 시스템에서는 성능 열화의 원인이 되는 원근 효과(near-far effect)와 다중 사용자 간섭(Multi Access Interference)에 대한 보상이 요구되며, 이러한 문제를 보상하는 방법으로 다중 사용자 간섭 제거를 위한 직렬 간섭 제거 기술이 제안된 바 있다. 그러나 이러한 직렬 제거 방식은 사용자간의 간섭 제거 횟수의 가변성으로 인하여 안정된 성능을 보이기가 어렵다. 본 논문에서는 이러한 단점을 개선한 방식으로 윈도우 기법을 적용한 직렬 간섭 제거 방식을 제안하고, 이에 대한 성능 평가를 수행하였다.

In this paper, we analyzed the serial interference cancellation scheme and proposed the new serial interference cancellation scheme suppressing multiple access interference. Compensating for the near-far effect and the multiple access interference is critical for the stable performance of DS/CDMA system, and the serial multiple access interference cancellation has been proposed as one of the compensation methods. But this serial interference cancellation scheme has a linear variation in the number of cancellation operation each users. Becaure of this variation, it is difficult to show a stable performance. Hence, we suggested a new serial interference applying window technique to overcome this fault and made a performance estiamation.
