The advantage of the multiframe message model is that it allows rich messages to be exchanged between communicating applications 多幀消息模式的優(yōu)點(diǎn)在于:它允許在通信應(yīng)用程序之間交換內(nèi)容豐富的消息。
It ' s the aim for many pepole to improve the image resolution . one of the proper approaches to the aim is the siginal processing based methods in software . it can recover the high resolution image from multiframe undersampled images 提高遙感影像的分辨率一直是人們追求的目標(biāo),實(shí)現(xiàn)這一目標(biāo)的有效途徑之一便是采用基于信號(hào)處理的軟件方法,其基本原理是應(yīng)用同一地區(qū)多幅重復(fù)觀測(cè)影像之間的互補(bǔ)信息,用超分辨率重建算法恢復(fù)高分辨率圖像。
Qe1 achieve the whole synchronization by software and hardware . during the course of the initialization of the qe1 system , the chip pm4354 can accomplish the task of synchronization of bit , frame and multiframe after the chip initialization by the software . after pm4354 accomplishes the bit synchronization , qel will read the status registers of the pm4354 to get the status of each el circuit and choose recovered clock of the specified the el circuit as the external timing source of the whole htc - 5200an equipment Qe1系統(tǒng)在系統(tǒng)初始化時(shí),通過軟件完成對(duì)硬件芯片pm4354的初始化工作后,便可利用該芯片完成4路e1的同步(位同步、幀同步和復(fù)幀同步) ;在pm4354完成時(shí)鐘提取的任務(wù)后, qe1通過不斷地訪問pm4354的狀態(tài)寄存器,獲得每路e1的狀態(tài)信息,在時(shí)鐘源的選擇原則下,選擇指定e1線路的恢復(fù)時(shí)鐘作為整個(gè)htc - 5200an節(jié)點(diǎn)設(shè)備的外部參考時(shí)鐘,從而解決了htc 5200an的中繼板卡由e1變?yōu)閝e時(shí)所帶來的網(wǎng)同步時(shí)鐘源。
In pon , the transmission of downlink signal from olt to onu is not complex . usually , the information destined for onus are combined into a multiframe at olt via tdm before reaching the feeder fiber , and then broadcast to each onu via the passive optical demultiplexor . upon receiving the downlink multiframe signal , each onu takes out the part of information for itself only 在無(wú)源光網(wǎng)絡(luò)中, olt到onu的下行信號(hào)的傳輸過程較為簡(jiǎn)單,一般在olt將需要發(fā)送到各onu的信息采用時(shí)分復(fù)用的方式組成復(fù)幀送到饋線光纖,通過無(wú)源光分路器以廣播的方式發(fā)送到每一個(gè)onu , onu收到下行復(fù)幀信號(hào)后分別取出屬于自己的那一部分信息。
multiframeとは意味:マルチ?フレーム multiframe meaning:[Electronics] A set of frames in a signal that are adjacent to each other in time (consecutive) and positioned according to an alignment signal. multiframe перевод:многокадровый объект, группа кадров
