摘要: 在數位用戶迴路(DSL)中,可將頻帶分割以上傳訊號與下載訊號,此上傳與下載時皆有部分頻帶沒有用來傳輸。在此篇論文中,我們利用使用頻帶上的訊號能量對干擾雜訊能量之比值(訊雜比),來設計時域等化器。我們將訊雜最佳化,由通道的頻率響應中可看出,此種方法能加強傳輸頻帶上的響應,在模擬中也可發現我們所提出之時域等化器設計不僅可以有效的縮短通道的等效長度也能夠有效的改善系統的傳輸率。
In DSL (Digital Subscriber Lines) application,
usually frequency division multiplexing is used to separate the
upstream and downstream signals. In either direction of
transmission, some of the frequency bands are not used for
transmission. Earlier results show that minimizing interference by
exploiting unused bands is usual for design TEQ. In this thesis, we
also consider signal power in the objective function. The time
domain equalizer (TEQ) is designed by maximizing signal to
interference ratio. We will see that the incorporation of signal
power will enhance the frequency response of the resulting channel
response in the transmission bands. A better transmission rate can
be achieved as demonstrated by simulation examples.
