  1. A qos - support protocol, m - dcf, and its schedule model are proposed. by providing different contention window for different classes, the higher class frames the higher access probability. the simulation proves that m - dcf has better performance than dcf protocol on system throughput, discard ratio, frame discard ratio of higher classes, average access delay of different classes

    提出了為不同等級幀提供不同競爭窗口的改進型dcf ： m - dcf協議，並給出了m - dcf的調度模型，通過採用不同的競爭窗口，為不同n西安電子科技大學博士學位論文:無線局域網和ip服務質量關鍵技術的研究的應用提供了不同的接入概率，保證了qos ;模擬結果證明了m一dcf在系統吞吐率、丟包率、高等級業務丟包率、不同等級業務的平均接入時延等方面都優于dcf協議。
  2. The advantages of using leo satellite are as following : on the one hand the satellite orbit is low, so the transmission delay is short, the power loss is small ; on the other hand the development of cell communication, multi - access, frequency multiplex and etc also provide a technique guarantee to the leo satellite - mobile - telecommunication. so the leo system is considered to be a satellite - mobile - communication system with a great future

    低軌道衛星是一種運行於1000公里左右的高空中的人造衛星，利用leo衛星實現個人通信的優點在於：一方面衛星的軌道高度低，使得傳輸延時短、路徑損耗小，多個衛星組成的星座可實現真正的全球覆蓋，頻率復用更有效：另一方面蜂窩通信、多址、點波束、頻率復用等技術的發展也為低軌道衛星移動通信提供了技術保障。
  3. Although many research results have been provided, there still are many fields need further research, such as remote access delay, system communication, false sharing of data

    雖然已有許多研究成果，但仍在遠程訪問延時、系統的通訊量、數據的假共享等問題的解決方面不盡人意。
  4. High speed uplink packet access ( hsupa ) is a new work item of technical specification release 6 in 3gpp. wcdma system. the techniques of this work item, i. e. node b controlled scheduling, hybrid arq with chase combining, shorter tti, are to improve the performance of uplink dedicated transport channels, i. e. to increase capacity and throughput and reduce delay

    在hsupa中通過採用基站nodeb控制調度、結合了軟合併的混合自動重傳請求（ harq ） 、更短的傳輸時間間隔（ tti ）等關鍵技術，不但增強了系統容量與覆蓋還使用戶設備（ ue ）能獲得更大的上行吞吐、更小的傳輸延時。
  5. Presently, the apon system adopts tdma as the access mode on the uplink. it requires not too much in terms of optical performance, but it requires more complex electronic equipment ( e. g., complex synchronized timing, ranging and delay control technolgies ) to avoid the collision of uplink information packets

    目前apon系統在上行通道中採用時分多址的接入方式，它對光性能方面的要求不高，但它要求更復雜的電子設備，如要求復雜的同步定時、測距和延時控制技術，以避免上行信息分組產生碰撞。
  6. In distributed system which is created by the replication technology of sql - server, users can access, update both local data and remote replicative data. but because of the delay through network, local concurrency mechanism ca n ' t be aware of real - time operational status of other computers. even if there are conflicts in the system, each site ca n ' t gain real - time information

    利用sql - server的復制技術構建的分散式應用系統中，用戶可以訪問、更新本地的及復制到本地的數據，由於網路傳輸上的延遲，系統的並發控制機制不可能實時地了解其它計算機上的操作情況，即使發生沖突，也不可能實時得到反饋。
