Hf manet is a kind of manet that uses short wave channel as the physics medium. mac layer protocols are the core of hf manet to become a network. link layer protocols mainly research on medium access protocol, mac address, automatic link establishment technologies, protocol data structure and data transmission protocol
鏈路層協議是短波自組織網技術的核心，其主要研究為通道接入協議、鏈路層地址標識、自動鏈路建立、協議幀格式及數據幀傳輸協議等。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。The mpls technology was raised just in order to make the most of the switching technology in the core of the network and the ip routing technology on the edge of the network. before presenting the solution of the mpls, there are many integration model, the basic method adopted by them were all carry the control information from the ip router, and combine it with the transmition capability and the label switching of the atm switching machine, accordingly constructing a high speed and economic multi layer switching router. but, all these solutions can not communicate and just suit for adapting the atm as the second layer transmiting link, can n ' t work on other interface ( fr, ppp, and ethernet ), this is obviously conflict with the developing way of the based on packet of the internet
多協議標簽交換（ mpls ）技術就是為了綜合利用網路核心的交換技術和網路邊緣的ip路由技術各自的優點而產生的。在mpls技術方案提出之前已有的各種集成模型解決方案所採取的基本方法都是從ip路由器獲取控制信息，將其與atm交換機的轉發性能和標簽交換方式相結合，從而構建成一個高速而經濟的多層交換路由器。但是，各種方案彼此不能互通，而且僅適用於以atm作為第2層的傳輸鏈路，不能工作在其他多種媒體（如幀中繼、點對點協議、以太網）中，這與internet基於分組的發展方向相矛盾。In recent years, with the development of communication technologies, digital protection devices are also improved. in this paper, the communications that are used in digital protection device and the protocol they followed are studied. as a kind of field bus technology, can ( control area network ) is applied to the communications of double mcu, which has higher reliability and strong transmission ability
同以往的通信技術相比， can信號傳輸採用短幀結構，每幀的有效位元組數為8個，因而傳輸時間短，受干擾的概率低，當節點嚴重錯誤時，具有自動關閉的功能，以切斷該節點與總線的聯系，使總線上的其他節點和通信不受影響，具有較強的抗干擾能力。Secondly, two kinds of typical 3d wavelet transform structure have been studied. it could further remove temporal redundancy by organizing multi - level mc temporal filtering. according to the motion characteristics of the video sequence, an adaptive gop structure is proposed
本文基於視頻序列的運動特徵，提出了一種自適應三維小波變換結構，該結構能夠根據視頻序列的運動劇烈程度自適應確定幀組大小。Data types 0 it shall be possible to represent a large range of data types, both with natural and synthetic origin, as well as any combination of these data types, e. g. still pictures, frame - based as well as arbitrarily shaped video, specific and generic 3d models, graphics, text, natural and synthetic audio, natural and synthetic speech, etc
數據類型:應能夠表示各種不同的數據類型，包括自然的和合成的，也包括兩者的組合.如:靜止圖像，其于幀的視頻，任意形狀的視頻，專用的和通用的3d模型，圖形，文本，自然聲音和合成聲音，自然語音和合成語音等分享友人
