In this protocol, the transmitter organizes the frame according to it, and the receiptor does validity check of the characters, length check, crc check. thus, the system will work more exactly and efficiently. and based on rs - 485 communication, the paper implements a process communication method, which is impulsed by overtime message of timers ’ check
在這種協議中,發送方根據協議組幀,接收方主要採用了字元合法性校驗、長度校驗、內容的crc校驗,提高了通信的效率及正確性,最後在rs - 485通信上實現了基於定時器超時檢測消息驅動的進程通信策略。The transmit circuit includes convolutional encoding, framing, differential encoding, shaping filter, pn generator, hopping pattern generator, etc. the main part of receive circuit is matched filter
發送電路包括卷積編碼、成幀、差分、成形濾波、 pn發生器和跳頻圖案發生器等;接收電路的主要部分是匹配濾波器。In chapter 5, the complex envelop simulation block diagrams of fh transmitter and receiver are presented at first. then key techniques of simulation system are discussed, including frame processing structure, fh sequence generator, etc. finally, simulation models of fh transmitter, receiver and jammer are presented. the influence of frequency excursion on performance of multi - tone continuous wave jamming is analyzed
第五章首先設計了跳頻發信機成員和接收機成員的復包絡模擬框圖;其次討論了跳頻模擬系統實現的關鍵技術,包括幀處理結構、跳頻序列發生器等;最後給出了跳頻通信發信機、接收機以及干擾機成員的模擬模型,分析了頻率偏移對多頻連續波干擾性能的影響。High - speed frame - synchronizer is an absolutely necessarily key device of the remote sensing satellite ' s ground - receiving system. it is mainly used to format the high - speed data stream, so that computer can get the beginning address of every frame of the high - speed data stream, and then data stream would be send to computer for pretreatment through high - speed interface
高速幀同步格式化器是遙感衛星地面接收系統中必不可少的關鍵設備之一,主要將從衛星接收到的高速數碼流格式化,使計算機得以辨識每一幀的起始位置,然後將數碼流經高速介面進入計算機進行預處理。( 2 ) data - processing module, its functions is using dsp processor to designdigital filter for the receiving signals, work out the root mean square values and phaseangle, then the phase compensation technique is applied to modify the signals, at lastexport the combining frame data. to data - output module. ( 3 ) data - output module, its functions is transmitting combining frame data toethernet controller, then send the data to the protective device
( 2 )數據處理模塊利用dsp處理器對接收到的數據信號進行數字濾波設計,求出相應的均方根值及相位角,並對信號進行相位補償,最後將數據組幀后傳給數據輸出模塊; ( 3 )數據輸出模塊將組幀后的數據傳送到以太網控制器,繼而發送給二次保護測控設備。During the period of up - stream transmission, the optical signals emitted from onu reach office center by fiber cable with different length. amplitude and phase of signals received are different. intervals between every framing signal are very short of only 30 bit, i. e. 192ns ( 155. 52mb / s ), the power difference of two signals can arrive at 15db ( g. 983 suggestions )
在上行信號回傳時,由於從各onu端發出的光信號是經過長短不一的光纜到達局端,所以接收到的各路幀包信號的幅度和相位都不相同,各幀包信號之間的時間間隔很小,僅30bits左右,即192ns ( 155 . 52mbps時) ,且兩路光功率之差可達15db ( g . 983建議) ,因此上行回傳需採用特殊的「突發模式光發射和接收」器件。分享友人
