블록호핑 SC-FDMA 시스템을 위한 순환지연 다이버시티의 지연값 결정 = Delay Determination for Cyclic Delay Diversity for Block-Hopping SC-FDMA Systems

국문 초록 (Abstract)

OFDMA 시스템에서는 순환지연 다이버시티는 다이버시티 효과에 의해서 시스템 성능을 증대시킨다. 그러나 블록호핑 SC-FDMA 시스템에서 순환지연 다이버시티의 적용은 다이버시티 효과에 의한 성능 증대효과와, 채널이 주파수 선택적이 됨으로 인한 성능의 감소효과가 동시에 발생한다. 따라서 시스템 성능을 최대화하기 위해서는 순환지연 다이버시티의 지연값을 적절히 선택하는 것이 필요하다. 이 논문에서는 이 두 가지 상반되는 효과와 블록호핑 SC-FDMA 시스템에서 순환지연 다이버시티를 적용할 때 순환지연값을 결정하는 방법에 대해 논의한다.

다국어 초록 (Multilingual Abstract)

In OFDMA systems, cyclic delay diversity can improve the system performance due to diversity effects. However, applying cyclic delay diversity to block-hopping SC-FDMA systems can affect the performance in two contrary ways: positive effect due to increased frequency diversity and negative effect caused by increased frequency selectivity. Hence, the delay value for cyclic delay diversity should be carefully selected to maximize the system performance. This paper discusses these two contrary effects and proposes a method of determining the delay value of cyclic delay diversity for block-hopping SC-FDMA systems.
