최근 효율적인 무선 멀티미디어 통신 시스템을 구현하기 위한 수단으로 CDMA/TDD(Time Division Duplex)를 이용한 코드분할 다중접속 방식이 주목받고 있다. 본 논문에서는 멀티미디어 트래픽을 효율적으로 수용하기 위해 CDMA/TDD 시스템을 위한 두 가지 시간 슬롯 할당 알고리즘을 제안한다. 실용적인 다중 셀 환경과 서로 다른 서비스 품질(QoS)을 갖는 여러 종류의 회선 교환 및 패킷 교환 서비스로 구성된 멀티미디어 서비스 모델을 가정하고, 제안된 알고리즘을 이용한 CDMA/TDD 시스템의 성능을 비교하고, 주파수 분할 이중화(CDMA/FDD)를 이용한 CDMA 및 TDD(TDMA/TDD) 시스템을 이용한 시분할 다중 접속의 성능을 비교한다. 우리의 컴퓨터 시뮬레이션 결과는 서로 다른 QoS를 가진 사용자 간의 간섭을 효과적으로 피할 수 있는 제안된 알고리즘 중 하나를 사용하는 CDMA/TDD 시스템이 다른 시스템과 비교하여 평균 지연 성능을 향상시킬 수 있음을 보여줍니다.

Abstract: Recently, code division multiple access scheme with time division duplex (CDMA/TDD) has drawn considerable attention as means to realize efficient wireless multimedia communications system. In this paper, we propose two time slot allocation algorithms for CDMA/TDD systems to efficiently accommodate multimedia traffic. Assuming a practical multiple cell environment and a multimedia service model which consists of several kinds of circuit-switched and packet-switched services with different quality of services (QoSs), we evaluate the average delay (average time from call generation to channel assignment) of the CDMA/TDD system with the proposed algorithms, and compare the performance with that of CDMA with frequency division duplex (CDMA/FDD) and time division multiple access with TDD (TDMA/TDD) systems. Our computer simulation results show that the CDMA/TDD system with one of the proposed algorithms, which can effectively avoid interference among users with different QoSs, can improve the average delay performance as compared with the other systems.
