Abstract
본 논문은 사용자 독립성을 보장하기 위하여 최근 다중 접속 기법으로 제시된IDMA(Interleave-Division Multiple-Access)에 관련된 기법을 제안하였다. IDMA에 제안된 기법은CDMA(Code Division Multiple Access)의 다양한 특징과 뛰어난 성능을 가지고 있을 뿐만 아니라 다수의 사용자가 시스템을 이용 가능하도록 데이터 검 파 원리에 기초한 저 비용의 MUD(Multi-User detection)의 실현을 가능하게 하여 고효율의 다중 접속 통신방식이 이루어 질 수 있게 하였다. 본 논문에서 제시된 시뮬레이션 결과는 코딩을 하지 않은 IDMA의 기법들의 결과를 나타내고 있다
Interleave-division multiple-access (IDMA) is recently proposed multiple access scheme, which employs random interleavers as the only method for user separation. As a particular case of code-division multiple-access (CDMA), IDMA inherits many distinguished features of well-studied CDMA, Moreover, it allows a very low-cost multi-user detection (MUD) based on a chip-by-chip detection principle applicable to the system with a large number of users, which is crucial for high-rate multiple access communications. Simulation results represented in this thesis is completely devote to the investigation of an un-coded IDMA scheme.
