Design of symmetric time - domain equalizers based on maximum shortening snr algorithm 基于最大縮短信噪比算法的對稱時域均衡器的設(shè)計
A method for training a time - domain equalizer having at least one coefficient that includes estimating a channel , initializing the at least one coefficient of the time - domain equalizer , updating the at least one coefficient of the time - domain equalizer with the estimated channel , retaining the updated estimated channel , fixing the updated value of the at least one coefficient of the time - domain equalizer for at least a one - symbol duration , calculating a modulated symbol based on an output of the time - domain equalizer , calculating a second value for the estimated channel based on the modulated symbol , setting the estimated channel to the second value , and repeating the step of updating the time - domain equalizer through the step of setting the estimated channel to the second value until a predetermined condition has been met 本發(fā)明系一種用以訓(xùn)練一具有至少一系數(shù)之時域等化電路之方法,讓方法包含估計一通道;初始化該時域等化電路至少一系數(shù);利用該估計通道來更新該時域等化電路之至少一系數(shù);保留該更新之估計通道;維持該時域等化電路之至少一系數(shù)之更新值至少一符號周期固定;根據(jù)該時域化電路之一輸出,計算一調(diào)變符號;根據(jù)該調(diào)變符號計算一用于該估計通道之第二值;設(shè)定該估計通道等于該第二值;及重復(fù)更新該時域等化電路至設(shè)定該估計通道等于該第二值之步驟,直到符合預(yù)設(shè)條件為止。
