Abstract

The feasibility condition of interference alignment (IA) for full-duplex (FD) multiple-input multipleoutput (MIMO) cellular networks is considered. The necessary and sufficient condition on the IA feasibility is established, characterizing the achievable sum degrees of freedom (DoF). The results demonstrate that FD operation with appropriate IA is able to improve the sum DoF on the conventional half-duplex operation.

본 논문은 전 이중 다중 안테나 셀룰라 네트워크에서 간섭 정렬 타당성을 다루고 있다. 간섭 정렬을 위한 필요충분조건 정립과, 달성 가능 합 자유도를 대칭 네트워크에 내에서 설명했다. 실험결과 기존 반 이중 통신의 합 자유도 보다 향상 되는 것을 확인 할 수 있다.
