| Abstract(in English) | This paper compares the down-link performances of several access schemes such as single-carrier (SC)/DS-CDMA, muiticarrier (MC)/DS-CDMA, and MC-CDMA in a land mobile broadband propagation channel for the IMT-2000 phase II. Computer simulation evaluated the packet error rate performance for each access scheme. As a result, frequency Rake diversity in MC-CDMA is more effective than time Rake diversity in SC/DS-CDMA in broadband environment due to a large amount of multipath interference. We also study the throughput defined as the achievable maximum transmission rate to maintain the packet error rate of 10^<-2> considering the guard band for neighboring system and the guard interval of MC-CDMA. The results show that MC-CDMA can achieve 1.8-3 times larger throughput than DS-CDMA and 4 sub-carriers MC/DS-CDMA achieves larger capacity compared with that of SC/DS-CDMA, when the required guard band width is 1.5 times as large as the sub-carrier bandwidth. |
