幀間間隙 的英文怎麼說
中文拼音 [zhèngjiānjiānxì]
幀間間隙
英文
interframe ga（ ifg ）-
It is composed of three mian protocols : call synchronization protocol, control frame transmission protocol based on arq mechanism and data transmisstion protocol based on slot precontract mechanism. one scan channel table is shared in the hfmanet. the nodes in the same dwell group work in the same scan channel, and the nodes in the different dwell group work in the different scan channel
該協議的網路拓撲結構採用分散式分群結構，協議不同於傳統的短波點到點及需要中心節點轉發的組網方式，而是初步實現了短波電臺之間多跳組網功能，其協議內容主要包括同步呼叫協議、基於arq的控制幀傳輸協議和基於虛電路及時隙預約方式的數據幀傳輸協議。Each time slot of the uplink frame contains a byte overhead, whose guard time is used to keep slight phase shifts from impairing the signal. the prepositive bit pattern is used for synchronization capture
在上行幀的每個時隙里有位元組開銷，其防衛時間用於防止微小的相位漂移損害信號，前置比特圖案則用於同步獲取。( 3 ) for the wireless channels subject to several types of fading existing in different time scales, the dynamics of channel conditions are decoupled into two random processes with different mathematic properties in different time scales. two algorithms in this scheme are proposed to dealing with each time scale : the resource optimizer allocates the resource to maximize the total revenue with price fairness and provide qos guarantees to applications, and the slot scheduler exploits the time variability of
（ 3 ）針對無線通道衰落的多時間尺度特性，將通道條件snr分解到不同時間尺度上，在不同時間尺度上針對不同的衰落特性來設計不同的演算法，完成不同的任務：在大時間尺度（幀）上進行資源分配，面向應用提供qos保證，保持應用間price公平性的情況下，尋求系統總收益utility的最大化；在小時間尺度（時隙）上進行時隙調度，利用各用戶通道容量的時變性，使各用戶獲得比平均通道條件情況下更高的吞吐量。The paper also analyzed the request access delay ( rad ) when using the bandwidth allocation algorithm, and found that the number of allocated contention slots has little effect on the rad, however the rad connected with the length of upstream time segment being depicted
論文還分析了在該帶寬分配演算法影響下的請求分組訪問延遲，發現請求分組訪問延遲受競爭時隙數的影響不大，而是與map幀所描述的上行時間段的長短有關。分享友人
