| 摘要: |
| ｘＤＳＬ是一种重要的基于现有的铜线环路的宽带接入网技术，而多载波调制是其中采用的一项重要的信号调制技术。本文分析了在ｘＤＳＬ中使用的２种多载波调制技术，对其性能做了比较，并得出了采用离散小波多音的方式在性能上优于离散多音方式的结论。 |

| Multicarrier Modulation Technology in xDSL |
|
| () |
| Abstract: |
| xDSL is an important broadband access network technology based on the existing copper lines, and multicarrier modulation is an important signal modulation technology used in xDSL. In this paper, we analyze two multicarrier modulation technologies used in xDSL, comparing the performance of these two technologies, and draw the conclusion that the performance of discrete wavelet multitone modulation is better than that of discrete multitone modulation. |
| Key words: Signal Modulation,xDSL, Multicarrier Modulation, |
