Abstract

In this paper, The existing interference alignment algorithms were analyzed in Rayleigh fading channel environment. The interference alignment techniques are divided to two parts. First thing is Iterative-method, another is Linear-method. Iterative method needs local channel info, but it has the constraint of iteration. On the other hand Linear-method must have global channel info, but has free of iteration and better performance. This paper evaluates the performance of interference alignment algorithms in Rayleigh fading channel of outdoor environment and WLAN channel based on IEEE 802.11n of indoor environment.

본 논문에서는, 기존에 연구되었던 간섭정렬 기법들은 주로 레일레이 채널 환경에서 분석이 이뤄졌다. 간섭정렬 기법은 크게 Iterative-method와 Linear-method로 구분되어 지며, Iterative-method는 반복이라는 제약이 있지만 채널정보가 적게 드는 장점이 있다. Linear-method은 광역 채널 정보(global channel info)가 필요하지만 반복에서 자유로우며 비교적 성능이 우수하다. 이 논문에서는 기존의 간섭정렬 기법들을 실외 환경의 레일리에 패이딩 채널과 실내 환경인 IEEE 802.11n 채널에 적용함으로써 성능을 비교하고자 한다.
