Taking frame error rate as an evaluation standard of communication performance , the dynamic coding protocol was designed which assures the reliability of communication 把誤幀率作為通信性能的評價標準,設計了動態(tài)編碼協(xié)議,保證了系統(tǒng)通信的可靠性。
First , in this paper , powercontrol technology is discussed , including its principle , methods of realization and status of research . then reverse outer - loop power controlarithmetic based on fer ( frame error rate ) measurement and adaptive variablestep - size inner - loop power control arithmetic are proposed . the simulation is doneand the result shows the deviation is smaller using the arithmetic fortracking the idealfer 然后在此基礎上給出了基于誤幀率fer ( frameerrorrate )測量的反向外環(huán)功率控制優(yōu)化算法和自適應變步長內(nèi)環(huán)功率控制算法,計算結果表明,與傳統(tǒng)的外環(huán)算法相比本文模型化的算法對目標fer的跟蹤具有較小的誤差。
According to similar ft3 frame format and its checkout mode of dnp data link layer , the relationship between fer ( frame error rate ) and ber ( bit error rate ) , frame length is deduced . the computation formulas of average transmission times and repeat transmission times guaranteeing the correct transmission of telecontrol information are given as well 根據(jù)dnp3 . 0規(guī)約數(shù)據(jù)鏈路層類ft3幀及其校驗方式,推導出幀傳輸失敗概率(誤幀率)與通道誤比特率和幀長的關系,同時給出平均傳輸次數(shù)和重復傳輸次數(shù)的計算公式。
