초록

본 논문에서는 ATSC 3.0 시스템의 $2{\times}2$ multiple-input multiple-output (MIMO) 송수신기 구조를 설계하고 성능을 분석한다. ATSC 3.0 시스템의 MIMO 방식은 송신기에서 입력 스트림의 역다중화 (demultiplexing) 및 프리코딩 (precoding)을 통하여 공간 다이버시티 (spatial diversity) 및 공간 다중화 (spatial multiplexing) 이득을 얻을 수 있다. 본 논문에서는 ATSC 3.0 MIMO 시스템의 프리코더를 이용한 송수신기 구조를 제시하고 전산 실험을 통하여 성능 결과를 제시한다.

In this paper, we design transmitter and receiver structures for a $2{\times}2$ multiple-input multiple-output (MIMO) in ATSC 3.0 systems and analyze the performance of the $2{\times}2$ MIMO system. In the ATSC 3.0 MIMO systems, spatial diversity and multiplexing gains can be obtained using the spatial demultiplexer and precoder. In this paper, we present the structures of the transmitter and receiver for ATSC 3.0 MIMO systems. Also, we present performance results of the $2{\times}2$ MIMO system through computer simulations.
