Abstract

This paper describes the physical layer modem structure of Giga KOREA 5G system which is being developed by ETRI as a 5G telecommunications prototype. The objective of Giga KOREA 5G system is supporting maximum 100 Gbps data rate for each cell with wide-bandwidth baseband station and mobile station prototypes in mmWave (10~40 GHz) environment. To achieve this objective, its physical layer is composed of high performance baseband station as well as mobile station and their OFDM TDD modems. The important features of Giga KOREA 5G physical layer are carrier aggregation, multiple receiving beam searching in mobile station, high data rate channel encoder and decoder and high speed modulation and demodulation functions.

본 논문에서는 밀리미터파 5G 이동통신 시스템의 일환으로 한국전자통신연구원이 개발중인 Giga KOREA 5G의 물리계층 모뎀의 구조에 대하여 설명한다. Giga KOREA 5G 기술은 셀 당 최대 100 Gbps급 용량을 가진 기지국으로 개인별 1Gbps급 모바일 서비스를 제공하기 위해 밀리미터파 (10~40 GHz) 기반의 광대역 이동통신의 원천기술 및 시제품을 개발하는 것을 목표로 하고 있으며, 이러한 요구조건을 충족하기 위해 물리계층은 고속 대용량 기지국 및 단말 플랫폼과 이에 탑재되는 OFDM TDD 방식의 고성능 모뎀으로 구현되었다. Giga KOREA 5G 모뎀의 주요 기능으로는 주파수 집성 및 단말의 수신 빔 탐색, 대용량 데이터 송수신을 위한 고속의 채널 부호화 및 복호화, 고속 변복조 기능 등이 있다.
