Abstract

본 논문에서는 세 명의 사용자가 존재하는 채널 환경에서 다중 송수신 안테나 시스템의 송신단에서 모든 사용자, 채널에 대한 정보를 완벽하게 알고 있다는 전제하에 목적지 이외의 인접한 채널이나 사용자로부터의 간섭을 먼저 제거하여 목적지로 정보를 송신하여 각 사용자들은 간섭의 영향을 받지 않도록 하는 비선형 전처리 부호화 기법을 소개하고, 이 중 가장 연구가 활발히 진행되고 있는 Tomlinson-Harashima 코딩에 기반하여 전처리 부호화기를 설계하고, 이의 성능을 더티 페이퍼 코딩 기반의 전처리 부호화기의 성능과 비교 분석하였다. In this letter, in order to reduce the inter-channel interference at the transmitted side, we design the precoder based on Tomlinson-Harashima coding, which is well know for one kind of non-linear precoding schemes, for 3-user MIMO wireless systems. And its performance is also analyzed in comparison with that of the Dirty Paper Coding based precoder.
