As a result , the inter - link between satellites is shared channel 這決定了小衛(wèi)星編隊星間鏈路是無線共享信道。
This is possible in part because remote objects share channels ; a remote object does not own a channel 這是可能的,部分原因在于遠(yuǎn)程對象共享信道;遠(yuǎn)程對象不擁有信道。
An effective media access control protocol for formatting satellite wireless shared channel is needed . chapter 5 advances a wireless token bus protocol 本文第五章提出了一種適用于衛(wèi)星編隊的無線總線令牌協(xié)議。
An efficient and effective medium access control ( mac ) protocol is essential as the shared channel is a scarce resource in mobile ad hoc network 在移動adhoc網(wǎng)絡(luò)中,共享信道是非常有限的資源,因而研究有效的mac協(xié)議對adhoc網(wǎng)絡(luò)具有重要的意義。
Radio equipment and systems - private wide area paging service - part 2 : functional characteristics and access protocol for private wide - area paging systems on shared channels ; english version ets 300719 - 2 : 1997 無線電設(shè)備和系統(tǒng).專用廣域無線電尋呼服務(wù).第2部分
A condition arising when two or more data stations attempt to transmit at the same time over a shared channel , or when two data stations attempt to transmit at the same time in two - way alternate communication 當(dāng)兩個或多個數(shù)據(jù)站想在同一時間通過共享信道發(fā)送數(shù)據(jù),或兩個數(shù)據(jù)站想在同一時間在雙向交替通信中發(fā)送數(shù)據(jù)時產(chǎn)生的一種狀態(tài)。
In wireless self - organized network ( ad hoc network ) , media access control ( mac ) protocol , which defines rules of how nodes can share channel with each other , is a key factor of improving the performance of ad hoc network 在無線自組織網(wǎng)絡(luò)( adhoc網(wǎng)絡(luò))中,媒體接入層協(xié)議( mac協(xié)議)控制著節(jié)點(diǎn)之間共享信道的規(guī)則,是提高adhoc網(wǎng)絡(luò)性能的關(guān)鍵因素之一。
The hardware and software are designed after designing the system ' s organization in the article . the measures of resisting interference are taken in both hardware and software , and the transmission format of the system signaling is provided . the theory of the shared channels configuration is analyzed , and the method of the shared channels configuration is given 本文在系統(tǒng)結(jié)構(gòu)設(shè)計的基礎(chǔ)上,設(shè)計了硬件和軟件;從軟、硬件兩方面采取了抗干擾措施;給出了系統(tǒng)信令的傳輸格式;對共用繩路配置進(jìn)行了理論分析,給出了共用繩路的配置方法;進(jìn)行了實驗研究。
Assigning serial different address code to different subscribers , useful signal is taken out of the same time slot and frequence , and is transmitted with one share channel . at received end , system makes use of completed address code from sending end to do correlative check and take out useful subscriber signal . the other address code signals are treated as broadband disturbing signal which is removed . in radio environment of existing variable disturbtion and muti - way declining , expand frequence signal ’ s broadband characteristics can improve system performance obviously . cdma mobile telecommunication system has some better characteristics , such as anti - disturbing 、 anti - way declining 、 secrecy 、 capacity 、 utilizing rate of frequence resource and so on , than other mobile telecommunication system Cdma ( codedivisionmultipleaccess )移動通信系統(tǒng)的技術(shù)基礎(chǔ)是基于擴(kuò)頻技術(shù)的碼分多址,通過給不同的用戶分配各自特定的地址碼序列,將處于相同時隙和頻率的用戶信號分離開來,采用共享信道方式傳輸信息。在接收端,系統(tǒng)利用與發(fā)送端完全一致的本地地址碼對接收信號進(jìn)行相關(guān)檢測,提取需要的用戶信號,而將其他使用不同碼型的信號視為寬帶干擾而從中剔除掉。
The internet is based on the sharing channel of tcp / ip protocol and consists of various heterogeneous subnets . it is unpredictable of its transportation latency , available bandwidth and data package lost rate . so it ' s necessary to have an efficient encoding method and an adaptive real time transportation strategy to meet the multimedia communication ' s requirement of latency and bandwidth Internet基于tcp ip協(xié)議信道共享,由多種異構(gòu)網(wǎng)絡(luò)互連而成的,其中的傳輸延時、信道帶寬、數(shù)據(jù)包丟失率都是時變的、不可預(yù)測的,因此,對延時、帶寬要求很高的多媒體通信,必須有一種高效的編碼方法和根據(jù)帶寬變化的實時傳輸策略。
