Trail trace identifier multiframe
路徑蹤跡識別復幀 -
The advantage of the multiframe message model is that it allows rich messages to be exchanged between communicating applications
多幀消息模式的優點在於：它允許在通信應用程序之間交換內容豐富的消息。 -
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
提高遙感影像的解析度一直是人們追求的目標，實現這一目標的有效途徑之一便是採用基於信號處理的軟體方法，其基本原理是應用同一地區多幅重復觀測影像之間的互補信息，用超解析度重建演算法恢復高解析度圖像。 -
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系統在系統初始化時，通過軟體完成對硬體晶元pm4354的初始化工作后，便可利用該晶元完成4路e1的同步（位同步、幀同步和復幀同步） ；在pm4354完成時鐘提取的任務后， qe1通過不斷地訪問pm4354的狀態寄存器，獲得每路e1的狀態信息，在時鐘源的選擇原則下，選擇指定e1線路的恢復時鐘作為整個htc - 5200an節點設備的外部參考時鐘，從而解決了htc 5200an的中繼板卡由e1變為qe時所帶來的網同步時鐘源。 -
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
在無源光網路中， olt到onu的下行信號的傳輸過程較為簡單，一般在olt將需要發送到各onu的信息採用時分復用的方式組成復幀送到饋線光纖，通過無源光分路器以廣播的方式發送到每一個onu ， onu收到下行復幀信號後分別取出屬于自己的那一部分信息。 -
Thereby, the choice of external timing source brought by the changing from the el to qel has been resolved. in the related chapters, the paper will explain the arithmetic of synchronization of bit, frame and multiframe in the pm4354 hardware and describe the software arithmetic and hardware sketch map of net synchronization
本文在相關的章節中將詳細地給出pm4354硬體上完成位同步、幀同步和復幀同步的實現的演算法，並給出qe1在實現網同步過程中的軟體演算法和硬體電路示意圖以及在項目開發過程中，測試以上各種同步技術是否可行的技術方案。 -
With the current condition, the paper raises the point of synchronization in the qe1 ' s development, including the synchronization of bit, frame, multiframe and network and analyses the performance frame synchronization system based on the theory of probability and finally explains the realization of the technology of synchronization. the hardware circuit diagram of qe1 and some software flow chart have been offered in the paper
在針對qe1中繼板卡系統實際的開發情況后，本文分析了該系統所涉及的同步問題（包括位同步、幀同步、復幀同步和網同步） ，在概率論的基礎上分析了qe1系統的幀同步系統的性能，並研究了各種同步技術在qe1中的實現。
