Abstract

In this paper, we propose a novel precoder selection technique for maximum-likelihood (ML) detected spatially multiplexed multiple-input multiple-output (MIMO) systems. Previous precoder selection techniques were designed without considering UEP, however the proposed technique is designed considering multi-antenna unequal error protection (UEP). Simulations demonstrate the improved multi-antenna UEP performance by the proposed technique.

본 논문에서는 maximum-likelihood (ML) 신호검출을 사용하는 공간다중화 multiple-input multiple-output (MIMO) 시스템을 위한 새로운 unequal error protection (UEP) 프리코더 선정기술을 제안한다. 기존 프리코더 선정기술들은 UEP를 고려하지 않고 설계되었으나, 제안된 기술은 다중안테나 UEP를 고려한다. 모의실험을 통해 제안된 기술의 적용에 따른 향상된 다중안테나 UEP 성능을 확인한다.
