短幀數據 的英文怎麼說
中文拼音 [duǎnzhèngshǔjù]
短幀數據
英文
short frame data-
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。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。3 standard adopted in ethernet designates 368 bits minimum data field size in mac fraae, filling bits will be loaded if data length is shorter than 368 bits, which causes extra spending. on the contrary, the naxiaub process data length in iec 61375 - 1 is only 256 bits. ( 2 ) actual ethernet rate may be lombps, loombps, looombps, which is far higher than 1vl consequently it is likely that csma / cd fulfill functions of mvb polling strategy
3標準指定的mac幀最短數據域長是368位，不夠時應裝入填充比特，造成不必要的開銷，而iec61375 - 1規定的最短過程數據僅為16位，最長不過256位； （ 2 ）由於歸一化速率為1mbps ，而實際的ethernet傳輸速率遠遠高於1mbps 。1 ) realization of software packet embedded in m - es and md - is respectively to accomplish main function of mdlp, including assignment of tei ( temporary equipment identifier ), establishment of multiple frame operation, framing, flow control and error - free transmission of packets, is detailed. 2 ) a test model is established to evaluate the robustness and stability of mdlp and verify the validity of software packets. 3 ) according to the design of radio modem construction used in m - es, the modules of interface between data terminal equipment and radio modem are achieved to enable transmission of short message and continuous pseudo - random bit stream via rs232 uart
本文首先概述了蜂窩數字分組數據網的結構和空中協議，詳細分析了移動數據鏈路協議，並在此基礎上，重點敘述了以下方面的工作： 1 ）設計並完成了分別應用於m - es和md - is端無線控制器的兩套程序實現數據鏈路層的主要功能，包括分配臨時設備號、建立鏈路、組幀和面向連接的服務保證分組正確無誤地傳輸，並進行適當的流控； 2 ）建立測試模型測試移動數據鏈路協議的可靠性和穩定性，證明了程序包的效用； 3 ）根據cdpd系統無線數據機的軟硬體總體設計方案，完成了介面模塊，實現了rs232異步串口通信，使用戶可以根據需要發送短消息或連續的偽隨機比特流； 4 ）在tms320c54x的軟體、硬體模擬平臺上，建立了cdpd試驗模型，實現了cdpd系統的mdlp基本功能。The system also includes a wavelet calculating module and a buffering module which is designed to transpose the storage. these two modules enable the system to calculate directly during carrying out the wavelet - transform without buffering the whole frame of image
轉置存儲模塊的功能是使得輸入數據無需等到整幀圖像傳完便可以進行小波變換計算，從而大大縮短數據從輸入到輸出所需要的延遲時間。分享友人
