摘要(中)傳統的CDMA/PRMA在低系統負載時有很短的通道擷取延遲,但高流量時卻有高封包損毀率,而CDMA/FRMA在高流量時卻有很好系統使用率然而在低系統負載時卻有高延遲,為克服此兩項做法的缺點,善用其優點,本論文提出了動態切換模式的概念,先依照系統中使用者人數調整不同的邊界值,並根據目前系統負載分為兩種不同的狀態,針對系統目前的狀態切換到最合適的操作模式,由於不同的操作模式可在不同的負載得到更好系統效能,藉此增加整體系統總容量及降低平均延遲,模擬驗證了此作法比 CDMA/PRMA 有更高的總容量及通道利用率而且其解決了 CDMA/FRMA 高傳輸延遲的問題。同時,在語音與資料封包混合的狀況下,加入了動態切換的概念使得 CDMA/ARMA在網路流量驟變的環境可得到更好的系統效能。
摘要(英)Although, traditional CDMA/PRMA system has low delay under light load, it suffers high packet corrupt rate under heavy load. On the other hand, CDMA/FRMA system suffers long delay in light system load but it obtains a better utilization under heavy load. To utilize the advantages of CDMA/PRMA and CDMA/FRMA system, this study proposes an adaptive packet reservation multiple access protocol (ARMA) for CDMA cellular system. According to system’s situation, the ARMA protocol adjusts to suitable operation mode. Simulation results demonstrate that CDMA/ARMA system obtains a significantly higher system capacity than CDMA/PRMA and a lower access delay than CDMA/FRMA system.
